The Color Segmentation/Region Filtering subsystem uses the Blob Analysis block and the Extract Face and Hand subsystem to determine the location of the person's face and hand in each binary image. The original image is segmented and the connected components are determined and visualized by color. You can easily create a GUI and run it in MATLAB or as a stand-alone application. Accordingly, only the Red eoniponent is considered as it provides a high capacity for color. In addition to the aforementioned analysis directions, the Hessian blob algorithm may find applications outside of the realm of AFM data analysis. Both algorithms rely heavily on Canny edge detection, but both also use other image processing techniques, such as defining an image threshold. Blobs can be described as a group of connected pixels that all share a common property. BW2 = bwperim(BW) returns a binary image that contains only the perimeter pixels of objects in the input image BW. Provide your first answer ever to someone else's question. The example then compares the blob with each warning sign detection template. All small insignificant blobs are removed.
