I need to write a script extracts the average intensity of each object in the rice.png. My use of regionprops has failed.

    I = imread('Rice.png'); %imports the image
    Background = imopen(I,strel('disk',15)); %removes the rice and displays the background as its own entity
    I2=I-Background; %removes the background from the image
    I3 = imadjust(I2); %increases the contrast of the image
    bw = im2bw(I3); %creats a binary image
    bw2= bwareaopen(bw, 50); %removes the noise from the image
    cc = bwconncomp(bw2, 4); %finds the connected part of the image and determins if they are the same or different
    cc.NumObjects % counts the objects
    bw3=bwlabel(bw2,4); %converts the image into a labeled bw code
    bwlabel2rgb=label2rgb(bw3); %converts above into rgb, without above the image is the same colour
    imshow(bwlabel2rgb); %displays image
    gray = rgb2gray(bwlabel2rgb);
        measurements = regionprops( bw,gray, 'MeanIntensity');

Here is my current code but I have no idea what the issue is, could someone please point me in the right direction?

What error message are you seeing? How do you know that the measurement has failed?

[Bradley Cory]

Error in test (line 13) measurements = regionprops( bw,gray, 'MeanIntensity');

[Walter Roberson]

Please show the complete error message. Also, which MATLAB release are you using?

[Bradley Cory]

Attempt to execute SCRIPT regionprops as a function: \\student\USR\Vol4\bc\Documents\MATLAB\regionprops.m Error in test (line 13) props = regionprops(bw,gray, 'MeanIntensity');

Matlab r2015b I think in the version?

Answer 1

[Walter Roberson]

You have your own regionprops.m file in \\student\USR\Vol4\bc\Documents\MATLAB\regionprops.m that is interfering with using the MATLAB regionprops.m

Thank you! Clearly I need more coffee
