Abstract: Conventional computer vision pipelines typically treat low-level enhancement and high-level semantic tasks as isolated processes, focusing on optimizing enhancement for perceptual quality ...

_, th2 = cv.threshold(img, 200, 255, cv.THRESH_BINARY_INV) _, th3 = cv.threshold(img, 127, 255, cv.THRESH_TRUNC) _, th4 = cv.threshold(img, 127, 255, cv.THRESH_TOZERO ...

but different resolution.e.g. searching face, eye in an image and it vary image to image so in this case we create a set of images with diff. resolution which is called pyramid. We also use these ...
