Description: 基于存在概率图的圆检测方法.提出了一种基于存在概率图的圆检测方法, 将图像边缘点共圆结构信息变换为圆存在概率图中的峰, 再通过峰值检测确定圆的参数。该方法能有效地检出边缘不清晰、不完整的圆形轮廓, 具有占用内存少, 阈值物理意义明确的特
点, 较好地解决了标准 HT 圆检测方法中占用内存空间大, 计算效率低的问题。实验结果表明圆存在概率图具有较强的稳定性和分辨能力.-Probability map based on the existence of circle detection method. Presents a probability map based on the existence of circle detection method to image edge points, a total of circular structure of the existence of information is transformed into a round map of the peak probability, and then through the peak detector to determine the parameters of a round. This method is effective in detecting the edge of unclear, incomplete circular profile, with less memory, the physical meaning of the threshold specific characteristics, a better solution to the standard circle detection method HT memory space, the computational efficiency of low- problems. The experimental results show that the existence of the probability circle map has strong stability and resolving power.

Description: 边缘检测是数字图象处理、图象分析和识别领域中的重要课题。近年来，由于彩色图象的广泛应用，使彩色数字图象处理技术日益收到关注，彩色图象边缘检测是在众多的彩色图象处理中极为重要的方法，这是因为图象分割、识别等大量的高层次彩色图象处理均建立在低层次边缘检测的基础上。本实验是将彩色RGB图象首先转换为灰度图象，然后利用经典的边缘检测算Canny算子来实现边缘检测，然后再统计出边界方向的直方图。-Edge detection is a digital image processing, image analysis and identification of important issues in the field. In recent years, due to the extensive application of color images, so color digital image processing technology increasingly received attention, color image edge detection in color image processing a large number of extremely important ways, this is because the image segmentation, identification such a large number of high-level color image processing are built on low-level edge detection based on. This experiment is the first color RGB image is converted to grayscale images, and then use the classical Canny edge detector operator to realize edge detection, and then the statistics of the histogram of the direction of the border.

Description: This project is about detecting edges using canny edge detector. The canny edge detector is implemented from scratch using c++. Steps involved in creating a canny edge detector: STEP 1: smoothen the image using gaussian blur. STEP 2: Use differential operator to find the magnitude and direction of every edge pixel. STEP 3: Non maximal supression or Thinning is done. Here the thick edges are supressed into thinner ones. STEP 4: Hysteresis Thresholding: Two thresholds are selected. pixels lower than the lowT will become zero. pixels higher than the HighT will become one. The candidate pixels will become one if they can be linked to any one of the strong pixel.
