Image Processing Crack Detection
Battaglia Navale Per Pc on this page. I have problem for detection for surface ceramics image, how i can detect crack surface, pls give me some advice.
Fast crack detection method for large-size concrete surface images using percolation-based image processing. Here we introduce a system which detects crack on wall by using image processing. As image is susceptible to noise we used some image preprocessing steps to detect.
Hi, I have written the following matlab code to do the following:- • load rgb image of surface • contrast stretch • convert rgb to gray scale • image segmentation • morphological operations (thin, clean, fill, etc.) • imtool for pixel length determination • Calculation of crack length based on calibration of image and above determined pixel lenght. My aim is to develop the SIMPLEST matlab code for automatic detection of cracks and estimate the length of the crack (if possible other geometrical properties) from a sample image. Thanks for your blob demo, helped alot!

I) Is the bwlabel function labelling ALL 4-5 cracks in the image under one label? If yes how do I make sure it labels each crack separately?
Ii) the area returned from regionprop function is it for ALL 4-5 cracks in image? If yes how do get the area for each crack separately? Iii) the bwboundaries function returns 34 boundaries how do plot these boundaries such that the edges of each crack is highlighted. Iv) finally based on all these can you clarify me on how to determine the length of each crack (4-5 as shown in the sample image)? It was not clear from your example.%% load image I=imread('two.jpg'); Igray = rgb2gray(I); figure,imshow(Igray) title('Gray image')%% Binarize level = graythresh(Igray); binaryImage = im2bw(Igray, level); figure,imshow(binaryImage) title('Binarized image')%% Labeling & regionprop labeledImage = bwlabel(binaryImage); measurements = regionprops(labeledImage, 'Area');%% Boundaries boundaries = bwboundaries(binaryImage); numberOfBoundaries = size(boundaries, 1). I have managed to label and plot out each crack and also get its boundaries and area.
