问题 im doing an android project with opencv library and im using superpixelslic algorithm.After i applied the algorithm on some devices the image looks like grainy like this: This is my superpixel code: newMat=new Mat(); Utils.bitmapToMat(image,newMat,true); SuperpixelSLIC x= Ximgproc.createSuperpixelSLIC(newMat, Ximgproc.SLIC,rows/9,(float)25); x.iterate(num_iterations); if (min_element_size>0) x.enforceLabelConnectivity(min_element_size); Mat mask=new Mat(); x.getLabelContourMask(mask,true);

问题 Let's assume A be, 1 1 1 1 1 1 1 2 2 3 3 3 4 4 2 2 3 3 4 4 2 2 2 3 4 4 4 4 3 3 5 5 5 5 5 5 I need to identify all the numbers which are adjacent to a particular intensity value. E.g. the intensities 1, 3, and 4 are adjacent to the intensity value 2. What is the effective way to do it in Matlab? I can use the following, glcm = graycomatrix(A) But if A have a larger number of intensity values e.g. 10000 graycomatrix will not be an efficient method. 回答1: You can build a mask with a 2D

问题 I would like to extract color, shape and texture features of superpixel segments of an image . Then, I would like to visualize those features in order to select the important features. I am using the code at this link: https://github.com/np-csu/SLIC-superpixel I would like to access each cluster of the segmented image like this study: http://www.pyimagesearch.com/2014/12/29/accessing-individual-superpixel-segmentations-python/ However, I couldn' t find the related part of the code. 回答1: The

Adjacent and non-adjacent superpixels for an superpixel in an image

After segmenting an image into N superpixels, I need to specify the superpixels that are adjacent or non-adjacent to one superpixel and determine this relationship for all superpixels. [L,NumLabels] = superpixels(A,200); How can I specify the adjacent superpixels for each of superpixels ? Update I have tried the solution @Cris Luengo introduced. However the following errors arised : B=imread('H.jpg'); [L,N] = superpixels(B,200); glcms=graycomatrix(L); k=glcms(:,50); %SupNum=50 [r,~]=find(k>0); aa=find(r==50); r(aa)=[]; Update 2 I followed the instruction in MATLAB help but it doesn't work for
