Auto Die Bonder (ADB) is often encountered in the IC package field, whose key technical difficulty lies in quickly and accurately locating the bonding positions of the chips. In this paper, a normalized cross correlation (NCC) algorithm based on image pixels has been used to address this problem. By using iterated algorithm with simplified expression, the modified NCC (MNCC) is remarkably accelerated...
In this paper, a new steganalytic method based on statistical distribution of pixel differences is proposed, which is designed to detect the presence of spatial LSB matching steganography in high-resolution natural images. This paper establishes a statistical model for the distribution of pixel differences in natural images based on the Laplacian distribution and estimates the number of zero pixel...
This paper presents a multi-resolution masks based pattern matching method for person identification. The system is commenced with the construction of multi-resolution mask cluster pyramid, where the mask size is chosen depending on the distance between two eyes, computed from the detected face. Experimental results show the effectiveness of the system with significantly higher precision, recall rates...
