FPGA-based Pattern Matching System, which supports a Camera. Link (Medium), was used to detect Flip Chip PCB defect patterns. For the automation of the vision inspection of the Flip Chip PCB production process, the system was optimized by implementing the vision library in IP, which is used to produce high speed processing FPGA-based systems and to detect defect patterns. the implemented IPs comprised of Pattern Matching IP, VGA Control IP, Memory Control IP and Parallel processing MAD Pattern Matching IP. Xilinx was used to process the image transmitted in high speed from Digital Camera, Vertex-4 type 1.6 million gate FPGA chip. It allowed the processing of 4Tap (2352(H) * 1728(V) *8Bit) image data transmitted from the camera without the need for a separate Frame Grabber Board[5] in the FPGA. In addition, it could check the 1Tap(588(11) * 1728(V) *8bit) image data on a PC via USB transmission out of 4 Taps. For pattern matching, it abstracted a 250256 area out of the 1Tap image, transmitted the image to each IP and displayed the Pattern Matching output result on a 7inch TFT-LCD.

the automatic detection of the lip contour is relatively a difficult problem in computervision due to the variation amongst humans and environmental conditions. In this paper we improve upon the classical methods by introducing fusion. Two separate methods are first applied, one based on edge detection and the other on region segmentation to detect the outer lip contour, the results from them are then combined. Empirical evaluation of the detection process is also presented on an image subset of the Valid database, which contains lighting, pose and speech variation with promising results.
An automatic method for identifying different variety of rice seeds using machine vision technology was investigated, and a detection system which was consisted of an automatic inspection machine and an image-processi...
