Abstract
This study intends to propose a method to take pictures of concrete surface using a recently popularized digital camera and patternize shade distribution for the deployed histogram through image processing in order to develop a generalized evaluation method evaluate concrete surface work. Through this method, it is determined that it is possible to seek for possibility to utilize it as a comprehensive evaluation criteria for concrete surface finish and suggest a logical approach for concrete quality evaluation. From the results of the study, the following conclusions could be earned : 1) Concrete surface has shown a histogram distribution of a simple structure with easy patternization different from general images. 2) It was possible to earn several patterns through normalization of the histogram on the concrete surface images. I could also see that from results of consistency works on pattern on the actual images, most of images are consistent to the designed patterns. In addition, as individual images showed characterized unique pattern for each type of image, it would be possible to develop a characterized evaluation technique.
