| Summary: | 碩士 === 國立中正大學 === 電機工程研究所 === 87 === In this thesis, a line-parallel array processor scheme utilizing the Hough transform for straight-line detection is proposed. This processor scheme can process the input image row by row or column by column and detect the positions of line and line segments efficiently and fast. Each processing unit performs only a 10-bits integer addition and hence does not need complicated circuits and more operations. The results of the Hough transform are stored in shift registers. Because each shift register is 1-bit, the number of circuits is more less. A software program is designed to simulate the hardwire structure of the array processors and shows good performance. The analysis indicates that our scheme is better than other straight-line detection array processors in terms of speed and area-time product.
