A Scene Change Detection Scheme Using Local x^2-Test on Telematics

This paper presents a method that allows for detection of all rapid and gradual scene changes. The method features a combination of the current color histogram and the local chi-test. For the purpose of this paper, the chi-test scheme outperforming existing histogram-based algorithms was transformed, and a local chi-test in which weights were applied in accordance with the degree of brightness was used to increase detection efficiency in the segmentation of color values. This method allows for analysis and segmentation of complex time-varying images in the most general and standardized manner possible. Experiments were performed to compare the proposed local chi-test method with the current chi-test method
