I have an Nx10 matrix. How can I split this into three equally sized matrices (by number of rows) ? Is this something the reshape command can handle? Thank you! IP 댓글 수: 0 댓글을 달려면 로
how do i divide an image into blocks? y = rgb2gray(imresize(imread('DSC_0009.jpg'),.2)); z = 255.0 - 1.0 * double(y); z = z ./5 ; z2 = imfilter(z, fspecial('average', 15)); z2(z2 > 35) = 35; z2(z2 < 30) = 0; surface(z2); shadinginterp; axisij; axistight...
matrix|row vector Image blocks, specified as one of the following. For distinct block processing,Bis a numeric or logical matrix withm*nrows. Each column corresponds to one block. For sliding neighborhood processing,Bis a numeric or logical row vector of size 1-by-(M-m+1)*(N-n+1). ...

S = qtdecomp(I) performs a quadtree decomposition on the grayscale image I and returns the quadtree structure in the sparse matrix S. By default, qtdecomp splits a block unless all elements in the block are equal. S = qtdecomp(I,threshold) splits a block if the maximum value of the bl...
This MATLAB function rearranges sliding image neighborhoods of size m-by-n into columns with no zero-padding, and returns the concatenated columns in matrix B.

In MATLAB environment, every variable is an array or matrix. You can assign variables in a simple way. For example, Open Compiler x = 3 % defining x and initializing it with a value MATLAB will execute the above statement and return the following result − x = 3 It creates a 1-...
The global column matrix of potentials, [Vg], can be partitioned into free (v1) and fixed (v2) parts. The free part contains np-nb potentials which are now initialised to zero. The fixed part contains nb potentials which are set to the values stored in matrix p. Sign in to download...
