How can i display my images and draw rectangles over regions of interests and get the coordinates?
What i want is to read an image and have it fixed on the screen, then manually draw rectangles on the regions of interest and have them outputed as coordinates of the rectangle as have the rectangle stay on the image to know which region of interest i marked. The first step is actually reading the image and f…
Replace the color of block in gray scale image in Python
I have an Image of 128×128 pixels in which, there are 1024 blocks of 4×4 pixels each. If the coordinates of the first block areblock1= im[0:4, 0:4], then I want to replace the colour of pixels into a specific pixel intensity(or colour),example-128. So what I want to do is I want to change the colour…
Divide the image into 4×4 blocks and save each coordinate in variable
I have an grayscale Image of 128×128 that I want to divide into 4×4 pixel non-overlapping blocks and I want to save coordinate of each pixel as variable like this- I know I can do it manually by defining variables, but I can use any for loop for making it faster? After that, I’ll find mean of …
Reconstruct Image from patches/tiles in python
I have a task where I have tiled an Input image using the code: After that I calculated the sum of all tiles and sort them in ascending order. I’ll take the sum.sorted[-20] as a threshold and set all tiles below that threshold to 0 in order to neglect background. So far everything works fine. Now I need…
Create an image using the pixels median fom other images
I have six images and I want to find the median of each pixel and create a new pic from it. I created a list of my images in this manner: and then I wrote a for loop like that: I’ve found that there’s a function that finds the median using numpy but I don’t know how to use it.
Resize image to maintain aspect ratio in Python, OpenCv
I’d like to get a 1000 x 1000 picture in Python from any input picture so that the input doesn’t lose it’s aspect ratio. In other words, I want to resize the input so that its longer dimension is 1000 pixels and “fill” the other dimension with the background color until it become…
Python open jp2 medical images – Scipy, glymur
