[Change detection is the process of identifying differences in a region by comparing its images taken at different times. It finds applications in several fields such as video surveillance, medical imaging, and remote sensing (using satellite imagery). Several change detection applications using...
[In this chapter, we consider pixel-based change detection methods. First, we provide well-known methods in the literature. Then, we propose two novel pixel-based change detection methods.]
[This chapter deals with change detection methods based on color or multispectral space transformations. They are based on Principal Component Analysis (PCA), Kauth-Thomas transformation, vegetation indices, and color invariants.]
[In this chapter, we provide two texture based change detection methods. In both methods, we calculate the texture descriptors for bitemporal images separately. In order to detect possible changes, we find their difference. We start with gray level co-occurrence matrix based texture descriptors...
[This chapter deals with change detection methods based on the structure information in bi-temporal images. We define the structure using six different methods. In the following sections, we explore each method in detail.]
[In previous chapters, we introduced several change detection methods working on different principles. They also had different assumptions. In this chapter, we provide a method to fuse the change maps obtained from these. We applied our fusion approach both in category (within a group) and...
[In this chapter, we provide experimental results obtained from all change detection methods considered in this study. We first explain the data set used in the experiments. Then, we provide performance results in tabular form for each change detection method in detail.]
[Two dimensional change detection methods are used extensively in image processing and remote sensing applications. In this study, we focused on these methods and their application to satellite images. We grouped change detection methods (based on the way they process data) under four categories...
