Drizzle (image processing) Puns

Can I expect an iPhone 8 to have better image processing now compared to when it was released? Genuinely curious since other companies tend to try to improve image quality with software updates.

Thanks and cheers!

Pretty much the title. I do have some experience with computer vision (CNNs, YOLOs, GANs...)

But I want to learn how to process the image data before building a model.

How is "Digital Image Processing" by Gonzalez? Is it beginner friendly? (I do have a good math background from a CS degree but still).

Might be the wrong sub, but thought I'd ask here first.

Question for those of you that use the combo of APP and Pixinsight: Are you using APP strictly for stacking? If so I assume you are saving the image in the linear state, ie no stretch.

Do you us APP's light pollution removal tool?

Hi, I'm a new owner of a OnePlus Nord. Great phone with one downside. The camera, when I take pictures they get altered or photoshopped in some way. When I view the picture I can see the changes being made. Looks like something is processing the image. When it's done, well it doesn't improve the image.

Example, when taking a picture of a group of people all the faces are being altered. All but one are in some kind of blur. Also the lighting is being changed.

This feels very odd. Is there a way to shut this down?

Hello my friends. I'm kinda new to processing.

I wrote this code where i have random colors. I can print them and i get something like this: (133, 149, 93)

Now if i want to save this image i want to have (133, 149, 93) in the filename as well.

I tried using save("image - " + colors + ".jpg") because i defined my random colors under colors.

The program works but don't save and i get the following:

processing.app.SketchException: TypeError: cannot concatenate 'str' and 'int' objects

at jycessing.mode.run.SketchRunner.convertPythonSketchError(Unknown Source)

at jycessing.mode.run.SketchRunner.lambda$startSketch$3(Unknown Source)

at java.lang.Thread.run([Thread.java:748](https://Thread.java:748))

I have the colors as colors = color(random(0, 256),random(0,256),random(0,256))

What should i change?

Sorry for bad explaining. Thank you for your help!

Hi all,

I tried taking my first astro image of M45 the other night, using a Sony A7C, a 70-200mm zoom lens and a Star Adventurer. I'm trying to process the data and I'm also trying to figure out the cause of some artefacts in the data so that I can try to reduce them the next time I take some images.

• ~2 hours integration (230x 30") @ ISO1000, 200mm, F4
• 100 Bias (1/8000", ISO1000, lens cap on)
• 100 Flats (ISO1000, exposed to roughly middle of histogram using T shirt and light box method)
• 100 Darks (30", ISO1000, lens cap on)

Stacked everything in DSS, stretched slightly in Photoshop (using levels) and stars removed in StarNet++.

There's a very strong gradient across the image and also a circular pattern centred on the frame which looks a lot like aperture blades? I'm not really sure on what to look for first in order to improve. I hadn't expected great results on my first try, but I am surprised to see so many artefacts that I can't figure out!

when i want to create a sticker pack, thru pc on ubuntu, i got a error about some error processing images. the images are correct. i seen some issues posted on github and it lead nowhere, any tips on how to fix this? thanks!

Hi, in past few days I noticed that when I want to upload an image anywhere (server or DM's) it uploads the image fast as usual but then it takes up to a minute to actually send it. It is stuck on "processing" after the image itself was uploaded.

Is there a way to fix this? I could just reinstall discord but I don't know if it will fix the problem.

Thank you in advance for help.

I've been tinkering today with my own little generative 'art' library in Python that uses
the PILLOW and NumPy libraries.

The library is brand new and currently can generate interesting noise 'art'. I'm proud of the inline images and am curious whether anyone on here can recreate or make something like those images ;)

How would you improve on this tiny new library?

My next algorithm will be a spiral version

All critiques welcome I've tried to make the algorithms as fast as possible by using NumPy arrays where possible.

I 'd like to gain some intuition and actual insight if someone has worked on audio, on why we haven't seen major breakthroughs in audio ML (tracking and localization) as we saw with Image processing and NLP. Ofcourse there is the issue of data and annotating which except for being a laborious task, it's also hard to define e.g how do you label a conversation of multiple individuals on a dinner table, but I would assume that if needed large corporations would attempt such a project.

It seems to me that either people convert data to images and use Image Processing methods or use Signal Processing. Does that mean Signal Processing is more lightweight and outperforms a prospective ML approach?

I am a python developer and very new to the web world. I wrote an imaging processing script in python using cv2 and I am thinking to host it as a backend service online to make some passive income.

My planned website is much like this one - https://visafoto.com/ where users can upload a picture and we process it at the backend using my python code, and then give it a preview to the user. If the user is satisfied, s/he needs to pay to download the processed image.

Other functionalities I wish my web app has are -

1. Provide free trail, but restrict to one time use for one ip address / one device, per day.

2. Use captchar to prevent bots.

3. Register an account and select different plans

4. Incorporate different payment methods, i.e., Credit card, PayPal, Google Pay, etc.

5. Prevent DDOS

6. Send the processed image to user's email

I know some HTML, CSS and JS, but I think nowadays people don't reinvent the wheel completely, right? So what could be my best option to quickly set up my web app including the above requirements? AWS? Any useful resources?

Thanks a million!

Hey guys, I'm trying to create render layers so that I can do some post processing of my animation before finalizing it into a short clip. I want to be able to edit colors, mist, diffuse, ambient occlusion - pretty basic post processing. What type of file do I choose when I render? What file supports passes in cycles? I know this is a pretty basic question but for some reason I can't find the answer :( please help me out and teach me what i'm doing wrong so that i can start doing it right. thank u thank u thank u

golem-bulk-image-handler goes through the process of handling images on Golem using the Python module Pillow - which is based on PIL.

The project is quite basic right now, with the only functionalities being resizing, rotating, and adding filters, but it is open for suggestions. It should be easy to follow, even for someone who hasn't requested anything on Golem previously.

It shows a simple example of how one could create their own application to run on Golem - more so than the examples themselves but is not documented as a guide in itself. A few common issues and explanations can be seen in the README.md file.

If you have any questions, suggestions, or anything of the sort - feel free to comment them below or let me know on Discord :)

I thought the r/docker subreddit might be interested in this project I just found!

What will you be doing with this PC? Be as specific as possible, and include specific games or programs you will be using.

I’ll be using it for data models (neural networks, image processing) and big data projects, which means python, Keras and that sort of thing

And I’ll be using it for gaming, During the Black Friday steam sales I bought red dead redemption 2, forza horizon 4, cyberpunk 2077, middle earth shadows of war and dying light, and I’m kind of waiting to build a strong Pc so that I can enjoy them on my first run and not get an okayish experience with my current Pc while I play at 20-30 fps on medium-high

>What is your maximum budget before rebates/shipping/taxes?

Top of the budget probably 2K€.

>When do you plan on building/buying the PC? Note: beyond a week or two from today means any build you receive will be out of date when you want to buy.

ASAP, but don’t mind waiting for sales, shortages etc

>What, exactly, do you need included in the budget? (Tower/OS/monitor/keyboard/mouse/etc)

Everything, I currently have a laptop and I’m making the switch to my first pc

>Which country (and state/province) will you be purchasing the parts in? If you're in US, do you have access to a Microcenter location?

I’m in Spain so from here, I suppose I could buy us/world components through Amazon and have them delivered here.

>If reusing any parts (including monitor(s)/keyboard/mouse/etc), what parts will you be reusing? Brands and models are appreciated.

None.

>Will you be overclocking? If yes, are you interested in overclocking right away, or down the line? CPU and/or GPU?

Nope, I’ve read about it but I’m not sure I can do it safely so I would rather not risk doing so

>Are there any specific features or items you want/need in the build? (ex: SSD, large amount of storage or a RAID setup, CUDA or OpenCL support, etc)

1TB of storage minimum.

I do need/want wifi

>Do you have any specific case preferences (Size like ITX/microATX/mid-tower/full-tower, styles, colors, window or not, LED lighting, etc), or a particular color theme preference for the components?

Nope, more focused on performance and value rather than aesthetics.

>Do you need a copy of Windows included in the budget? If you do need one included, do you have a preference?

Yes, windows 10 is fine.

>Extra info or particulars:

If it’s helpful to orientate, my current laptop specs are

Processor: intel

This topic has been frustrating me. I'm really unsure of the proper way to process my raw image files before running them through photogrammetry software. Typically, what I've been doing is color correcting (using a ColorChecker card) and, sometimes, adjusting exposure before converting my raw files into 16-bit TIFs.

I'm interested in producing models that can be used for academic research, so I'm really concerned about whether what I do in raw processing has a negative impact on the accuracy of my models.

In some tutorials, I've seen people turning down highlights and turning up shadows. I understand that this will make more information available to the photogrammetry software, but could it affect model accuracy?

Recently, I purchased DxO PhotoLab 5 and I've tried out the DeepPRIME denoising. I've also noticed corrections for vignetting, chromatic aberration, and lens sharpening. I know I'm not supposed to use distortion correction, so I know to not enable that. However, what about the other settings; is there any benefit to enabling those or should they stay disabled?

Does anyone know of any published raw processing workflows for photogrammetry?

Again, I'm concerned that some adjustments may be suitable if one is producing gaming assets, but not suitable for producing models that may be used for collecting research data.
