Metamorphic Testing of Image Region Growth Programs in Image Processing Applications

Image region growth is one of the most important functions in image processing applications. However, due to the uncertainty of operation and large volume of data, it is difficult to obtain the test oracle of image region growth program. In order to alleviate the test oracle problem, this paper applied the metamorphic testing method into image region growth program testing and proposed a series of metamorphic relations by analyzing the geometric properties, numerical calculation features and specific implementation characteristics of the algorithm. The effectiveness of the identified metamorphic relations in eliminating different types of mutations is verified through case studies. The experimental results show that this method can effectively solve the test oracle problem of image region growth program.
