摘要：Straight line detection in a digital image is one of the important preprocessing step in computer vision and pattern recognition. Varying lighting conditions and noise makes line detection challenging. In this paper randomized line detection algorithm is been modified to overcome the limitations such as manualisation of the inputs with respect to minimum line length and number of lines need to be detected. The algorithm described in this paper instantiates after selecting a first nonzero pixel by row scanning and draws a strip from the reference pixel to any other pixel at the boundary of the image. Then the strip is rotated by 360o with predefined step angle. After each step, length of the strip is noted and compared with the previous strip length. Finally strip with the maximum length is considered. This process continues till the last nonzero pixel in defined image reaches to obtain a line detected image
