A VQ-based approach to thermal image analysis for printed circuit boards diagnosis

This paper proposes a novel method to analyze the thermal image of a printed circuit board (PCB) for fault detection. In this method, a gold thermal image is first generated from the thermal images of the PCB in normal operation, and then compressed into a codebook with a certain number of codewords...
