WebRead image as an array. Split the image in small patches. Convert the array patches in jpg (while keeping the same number of pixels) Perform detection on jpg patches. Each detection returns the top-left pixel of the detected box in patch coordinates. Convert the coordinates of the detected object from patch coordinates to image coordinates.

WebJul 23, 2012 · Feature detection - Small item in a large picture. Assume you have two images. In one you have a small icon (like less than 300X300 pixels). The second is a very large one, and in within you have one (or multiple) smaller instances of the icon (of course at different scale, rotation). The task at hand is to find the instances of the icon in the ... WebAug 1, 2024 · Meng et al. [15] proposed a method for detecting small objects from large images.
