QUESTION
im looking for this problem the last 2 days but didnt find any solution. I prepared this jsFiddle for you to show you my exact problem.
How do I make the image only visible for section 2? Like it should scroll behind the layer of section 1. It works from section 2 into section 3 but i cant find a solution to place it behind section 1.

QUESTION
Our project uses images with bit depths higher than 8 bits, typically 10 bit. These are stored with 16bit PNGs, with P3 colorspace (so 1024 colors per channel).
I am trying to show these images in a browser using WebGL2. So far having no luck. I know Chrome can do it as I have some test images which reveal an extended colour range on my Macbook's retina screen (but not on an 8bit, external monitor).
Here's the test image: https://webkit.org/blog-files/color-gamut/Webkit-logo-P3.png (Source: https://webkit.org/blog/6682/improving-color-on-the-web/)
If you're using an 8 bit screen and hardware, the test image will look entirely red. If you have a high bit depth monitor, you'll see a faint webkit logo. Despite my high bit depth monitor showing the logo detail in Chrome, a WebGL quad with this texture applied looks flat red.
My research has shown that WebGL/OpenGL does offer support for floating point textures and high bit depth, at least when drawing to a render target.
What I want to achieve is simple, use a high bit depth texture in WebGL, applied to an on-screen quad. Here's how I am loading the texture:

You can not (as of June 2020) create a canvas that is more than 8bits per channel in any browser. There are proposals but none have shipped
You can not load > 8bit per channel images into WebGL via
img
orImageBitmap
. There are no tests that data > 8bits makes in into the textures.
You can load a > 8bit per channel image into a texture if you parse and load the image yourself in JavaScript but then you fall back to problem #1 which is you can not display it except to draw it into an 8bit per channel canvas. You coud pull the data back out into JavaScript, generate a 16bit image blob, get a URL for the blob, add an img tag using that URL and pray the browser supports drawing it with > 8bits per channel.
QUESTION
I am trying to make the background of the square headers (The black bar that contains TERMS PONUMBER PROJECT) white and the text within black.
I have tried using the findContours method to find the contours and then crop and invert them so that I get them in the black text and white background form. But the problem is I am not having any idea on how to proceed ahead or is there any better approach to this
...ANSWER
Answered 2019-Sep-13 at 00:11Here's a simple approach
- Convert image to grayscale and Gaussian blur
- Otsu's threshold to obtain binary image
- Find contours
- Filter using the number of corners and contour area
- Extract ROI, invert ROI, and replace into original image
The idea is that if the contour has 4 corners, it must be a square/rectangle. In addition, we filter using a minimum contour area to ignore noise. If the contour passes our filter then we have a desired ROI to invert. The detected ROIs
Now we extract each ROI using Numpy slicing. Here's each ROI before and after inverting
Now we simply replace each inverted ROI back into the original image to get our result
