Jul 16, 2015 · In case you do not have the toolbox, you can use some basic MATLAB functions to obtain the desired image. However, you will need to know the threshold values for 'hue', 'saturation' and 'value' to filter the image for specific color range. Refer to the following script: This example shows how to refine a logical segmentation mask by converting it into a Freehand ROI object. In this method, you take advantage of the interactive reshaping capbility of the Freehand ROI object to make a better fit of the edge of the segmentation mask to the shape of the image region that you want to segment.
roi is the handle to the object generated by imfreehand. One of the methods (~functions) available through the object (using the handle) is createMask, which can be accessed with the. operator. The method generates a type logical array of the same size as the pixel dimensions of the image. % eventdata reserved - to be defined in a future version of MATLAB % handles structure with handles and user data (see GUIDATA) %Global variables used from other functions or declared as global to be

Nov 06, 2012 · I am currently working on the project of object recognition using matlab. but i am not getting how to draw circle with specific radius on specific image. i had calculated the centroid of the image, and using these as my center point i want to draw circle. please assist me. Create a binary mask from the ROI using createMask. The createMask function returns a binary image the same size as the input image. The pixels inside the ROI are set to 1 and the pixel values everywhere else are set to 0.
HI, I have a GUI in which I can select multiple regions of interest for an image. I have selected 3 regions in the image. I tried to get the binary image consisting of 3 regions. Error with using createMask. Learn more about createmask Image Processing Toolbox
