This matlab project segments leaves from a plant using varios pre-processing techniques followed by the watershed segmentation algorithm. CED aims to satisfy three main criteria. image thresholding, The Canny method applies two thresholds to the gradient: a high threshold for low edge sensitivity and a low threshold for high edge sensitivity. . The most powerful edge-detection technique that edge provides is the Canny method. The Canny method differs from the other edge-detection methods in that it uses two different thresholds (to detect strong and weak edges), and includes the weak edges in the output only if they are connected to strong edges. color profile, Free Open Source Codes Forge and Sharing CodeForge com.
