I work in a research lab and am currently setting up a system to image objects approximately 30 microns in diameter with a 250x USB microscope, then use image subtraction to isolate the objects as they move past the microscope FOV, and use blob detection to detect the object's presence in the binary subtracted image.
The microscope can capture still images at 1280x720, but video can only go up to 640x480. Ideally I wanted to take rapid still images (~10 FPS) at 1280x720, but various issues are preventing me from doing that. Capturing rapid images at 640x480 on the other hand is easily doable, but I'm not sure if the images would be clear enough for the image processing to resolve the objects at that resolution.
Would capturing the images at 640x480, then resizing them to 1280x720 before processing them, improve the ability to detect/resolve the objects in the image?
