Hi everyone,
I need help in this code that I wrote in shadow detection but the function is stoping in the (IF)
and send the message
Operands to the || and && operators must be convertible to logical scalar values.
Error in ziad (line 46)
if( w>=alphaV || w<=betaV || sat<=-0.3 || hue <=0.2)
clc
clear
mov = VideoReader('car_s.avi');
path1='ziad\VideoFrame\';
path2='ziad\cfhue\';
path3='ziad\cfsatur\';
path4='ziad\cfValue\';
path5='ziad\imagesinRGB\';
mkdir(path1);
mkdir(path2);
mkdir(path3);
mkdir(path4);
mkdir(path5);
alphaV=0.2;
betaV=0.8;
[m,n]=size(mov);
single=zeros(m,n);
%
n=0;
while hasFrame(mov)
frame = readFrame(mov);
pf5=strcat(path5,num2str(n),'.jpg');
imwrite(frame,pf5)
bac=imread('C:\Users\Dr.Zee\Desktop\Shadow detection\ziad\imagesinRGB\23.jpg');
bchsv=rgb2hsv(bac);
bchue =bchsv(:,:,1);
bcsat =bchsv(:,:,2);
bcVal =bchsv(:,:,3);
im=rgb2hsv(frame);
pf1=strcat(path1,num2str(n),'.jpg');
% figure(1)
% imshow(im);
