houghline transform, it it uses canny edge detection and hough transform. It then places a red line over any detected straight lines.

基于OpenCV的hough变换检测图像直线,本代码能够识别焊缝跟踪功能。-OpenCV based hough transform to detect linear image, the code can identify seam tracking.

针对自然生长状态下的成熟苹果图像的识别问题，提出选用R-G色差模型，改进的Ostu最大类间方差法分割图像。 然后用面积阈值法消除噪声，获取成熟苹果果实的目标区域。然后采用基于OpenCV的圆形Hough变换方法对多个粘连苹果果实进行分离。-For image recognition problem ripe apples natural growth state, the proposed selection of R-G color model between improved Ostu Ot
