For the microscope images, we can use a binary matrix where each pixel
corresponds to either black or white.
For the dye sensor images, we can use a sparse representation.
We’ll only store the coordinates (x, y) where the dye is detected, instead of storing the entire image.
We can use a list of tuples or a dictionary
Microscope image: 100,000 x 100,000 bits
Dye sensor image (sparse representation): Depends on the number of dye-detected pixels.
