I have a fractography image. I want to determine the edge detection in the fractographs... I want to compare the edge detection filters in matlab( sobel, prewitt,canny).. The following code is written
close all
a = imread('3.png);
imshow(a)
figure
imedge = edge(img, 'sobel',0.05);
imshow(imedge, 'ColorMap', [1 1 1; 1 0 0]);
figure
title('sobel');
img = imread('3.png');
imedge1 = edge(img, 'prewitt',0.05);
imshow(imedge1, 'ColorMap', [1 1 1; 1 0 0]);
figure
title('prewitt');
img = imread('3.png');
imedge2 = edge(img, 'canny',0.05);
imshow(imedge2, 'ColorMap', [1 1 1; 1 0 0]);
figure
title('canny')
Ending up in the error
Error using images.internal.imageDisplayValidateParams>validateCData (line 115)
Multi-plane image inputs must be RGB images of size MxNx3.
Error in images.internal.imageDisplayValidateParams (line 27)
common_args.CData = validateCData(common_args.CData,image_type);
Error in images.internal.imageDisplayParseInputs (line 78)
common_args = images.internal.imageDisplayValidateParams(common_args);
Error in imshow (line 246)
images.internal.imageDisplayParseInputs({'Parent','Border','Reduce'},preparsed_varargin{:});
Error in ruoc (line 3)
imshow(a)
Please anyone suggest the code/command for this.. Any help is much appreciated..
Please find the attachment of the image...
