I work on converting foot pressure sensor data to images to use in the deep learning model. the problem is the colors of the image are only the grades of blue, I want to change the numbers(sensor data) pixel representation with another more accurate scale. my data is between 0 and 1.
But the change is very small like I have some values 0.00873 and others 0.9342, so I need to choose colors that are very sensitive to my data as when converting it into pixels the difference will appear more.
Attached is a sample of the images I generate, each image have 4 pressure sensor for both the right and left foot.
The one to the left, I tried rgb2hsv but also appeared only with different grades of blue.
