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 crack more accurately. System works on most image formats. System mostly focuses on intensity value. This is done for sake of accuracy. System removes all undesirable noise. To detect crack, image is binarized and holes are filled so that image is more clearer to detect cracks. All small insignificant blobs are removed. Using blob analysis methodology, we detect number of connected objects. Based on the connected components system detects whether image contains crack or not. System is able to detect deeper as well as minor cracks. System uses many image processing steps to detect the cracks. Once the crack is detected by the system, System applies bounding box technology to display the crack to user. Thus , this is an innovative approach to detect crack on wall. We used image preprocessing steps as well as crack detection method to get accurate result. The proposed system is able to detect deeper cracks with 80% success rate and minor cracks with 50-60% accuracy.
Advantages- Involves preprocessing steps as well as crack detection method to get accurate result
- Detects deeper as well as minor cracks.
- Fails to work properly on poor quality images.
- Reduced accuracy in shadowed or poor lighting walls.

A Matlab toolbox for Road Crack Detection and Characterization
About:
Roads are important man-made infrastructures playing a very efficient role in populations' development, allowing the easy mobility of people, goods and merchandises. However, pavement surface exhibits distresses due to their constant usage. Hence, the maintenance of road networks is an essential task to ensure the correct pavement performance. To establish a proper maintenance policy of road networks, it is necessary to implement an adequate information system that allows supporting the management of their maintenance, capable of dealing with several interdependent data. The type and extension of pavement surface distresses are considered the most important data about pavement surface condition, necessarily to be collected during periodic road surveys. Images of road pavement surface (taken during periodic road surveys) are considered an important source of information for the quantitative and qualitative distress evaluation on road pavement surfaces, allowing the adequate identification and quantification of road pavement surface distresses. The proposed toolbox (developed under the MatLab environment) allows the automatic processing of images of pavement surface for the detection and characterization of road cracks (considered the most common pavement surface degradation found by road inspectors).
This toolbox is the result of research work developed at the Multimedia signal Processing Group of Instituto de Telecomunicações, on the detection and characterization of cracks in flexible road pavements.
Highlights:
·Includes a tool to help a human operator label blocks of road pavement surface images as either containing crack pixels or not, thus creating the ground-truth needed for a quantitative analysis of the results obtained;
·Capable to handle images acquired from different types of imaging sensors (active and non-active remote seining sensors);
·Allows the detection of cracks using two types of strategies: block-based (images divided into non-overlapping image blocks) and pixel based;
·Allows the implementation of a pattern recognition system to detect cracks using a two-dimensional block-based feature space (block-based approach);
·Allows the implementation of a segmentation by thresholding technique to detect crack at pixel level (pixel-based approach)
·Includes a strategy for the automatic selection of images for training a system, when pattern recognition techniques are used to detect cracks;
·Includes a crack linking strategy, allowing to group different connected components belonging to the same crack at pixel-based;
·Includes a crack type classification algorithm, to automatically characterize the detected cracks as longitudinal, transversal or miscellaneous;
·Includes a crack severity labeling procedure, based on the crack's width computations.
