A Multi-focus Image Fusion System for LED Detection

For micro-LED chip detection, Traditional method to check micro-LED chip is to observe manually through the microscope, but there will be blurred areas in image due to the limited depth of field. To solve this problem, a multi-focus image fusion system is proposed to obtain a sharp image of LED chip by fusing images with different in focus. Through the multi-focus image fusion system, the problem of blurred image caused by limited depth of field is solved, and the fused digital image is easy to observe and save.
