How can I get pixels info like the function "impixel", but for multiple pixel?

2 次查看(过去 30 天)
I want to get a plot of RGB info as a function of location (x,y), by drawing a line. (In impixel I need to choose one pixel, but I want a line of pixel)
Thank you.

plot(squeeze(image(:,column,1)),'r')
hold on
plot(squeeze(image(:,column,2)),'g')
plot(squeeze(image(:,column,3)),'b')
xlabel 'Column nmumber'
figure
plot(squeeze(image(row,:,1)),'r')
hold on
plot(squeeze(image(row,:,2)),'g')
plot(squeeze(image(row,:,,3)),'b')
xlabel 'Row nmumber'
