x=imread('C:\project folders\foot data\mesh1.jpg'); imshow(x) red=x(:,:,1); green=x(:,:,2); blue=x(:,:,3); figure(1) subplot(2,2,1),imshow(x);title('original image'); subplot(2,2,2),imshow(red);title('red'); subplot(2,2,3),imshow(green);title('green plane'); subplot(2,2,4),imshow(blue);title('blue plane'); %2nd to try and get it black and white figure(2) level=0.19;% try and tamper with this percentage to the the image as perfect as possiable bw2=im2bw(blue,level); subplot(2,2,1),imshow(bw2);title('black and white'); %now remove noise %fill the holes fill=imfill(bw2,'holes'); subplot(2,2,2),imshow(fill);title('holes filled'); %remove any blobs on the border of the image clear=imclearborder(fill); subplot(2,2,3),imshow(clear);title('cleared borders'); %removing lower pixels se=strel('disk',7);%7 is the value of pixels u can tamper with it based on the image resloution open=imopen(fill,se); subplot(2,2,4),imshow(open);title('remove small blobs'); %measure of the length props = regionprops(open,'Area'); figure(3) imshow(open) bwarea(open)

I would like to get the game measurements from the first image into the second I did the flittering and the gray scaling but get get the measurements.
