Calculate the code for the rice particles in a picture.How should I apply it to the video?
clear; clc;
% Read the picture rice.png
I=imread(‘rice.png’);
% Get the background of the picture
BG=imopen(I,strel(‘disk’,15));
% Get a picture with a uniform background
I2=imsubtract(I,BG);
% Get a binary image
level=graythresh(I2);
BW=im2bw(I2,level);
% labeled is the processed matrix, and numObjects is the number of rice grains;
[labeled,numObjects]=bwlabel(BW,8);
% Take an empty matrix A to store the number of pixels occupied by each grain of rice;
[m,n]=size(labeled);
A=zeros(numObjects,1);
% This loop is used to count the size of each rice grain, for example, the size of the i-th rice grain is stored in A(i);
for x=1:numObjects
for i=1:m
for j=1:n
if labeled(i,j)==x
A(x)=A(x)+1;
end
end
end
end
