Matplotlib displaying RGB pixels weirdly Question: I have a set of RGB pixels I gathered from an image, but when I try to save them and display them, they come out very weirdly, as 3 separate colors. It seems like it’s not reading my array as a list of RGB values. I have an abbreviated …
RGGB (x,y) –> RGB = (x/2,y/2,3) Question: The output of a camerasensor is SRGGB12. import numpy as np rggb = np.array([[‘R’, ‘G’, ‘R’, ‘G’], [‘G’, ‘B’, ‘G’, ‘B’], [‘R’, ‘G’, ‘R’, ‘G’], [‘G’, ‘B’, ‘G’, ‘B’]]) test2 = np.chararray((3, 4, 4)) test2[:] = ” test2[2,::2, ::2] = rggb[1::2, 1::2] # blue test2[1,1::2, ::2] = rggb[0::2, …
Is there a way to generate a RGB color by inputting R, G, and B values from 0 up to 255 without using the matplotlib module in python? Question: Is there a way to generate a color based on its RGB values rather than the following snippet? (And preferably with a more compact module than …
Numpy masking in 3 channel array Question: The following Snippet will create a test image # Create 3x3x3 image test_image = [] for i in range(9): if i < 6: image.append([255, 22, 96]) else: image.append([255, 0, 0]) Out: array([[[255, 22, 96], [255, 22, 96], [255, 22, 96]], [[255, 22, 96], [255, 22, 96], [255, 22, …

(PYTHON, PILLOW) How to make RGBA image conversion to RGB faster? Question: I’m making fade effect by merging .png image with .jpg, but the conversion process takes too long. Is there a way how I could speed up this process? for f in range(101): print(str((200 + f) /3) + "%") if f == 0: im_rgba …
How can I get one percent for 3 different values? Question: I have this code and it’s supposed to be a color picking game where you can edit different rgb values with the keys:"asd" and "jkl". I want it to give points based on time and accuracy and stuff but I also want a meter …
RGB Data in Scatterplot Question: I posted a question yesterday and was able to piece a few things together but I ran into another snag today. Essentially, I am trying to create a random 2D grid of RGB pixels, plot the RGB data into a 3D Grid to look for patterns and then analyze the …
PIL image to numpy Question: I have a NumPy image (2 dimensional) where each pixel range is in thousands. I want to convert it to an RGB image (3-dimensional), with a range from 0 to 255. so I did the following: from PIL import Image import numpy as np image = Image.fromarray(input_image,’RGB’) new_image = np.asarray(image) …
