In this paper, a scheme for BGA inspection is presented to address the challenges. First, we introduce an adaptive thresholding and a median-based Otsu method to separately determine the optimal threshold for segmenting each ball. Then, a reference-free path-walking mechanism is proposed to recognize locations of the balls in the grid.
