A Nonparametric Approach for Histogram Segmentation

WebbHistographic Segmentation. Histographic segmentation offers the opportunity to interact with multiple datasets mapped on a two-dimensional histogram and to distinguish features of interest and then select clustered data values to create regions of interest. With this tool, you can quickly segment a dataset by selecting clustered data values ... WebbFirst, the histogram is divided into several sub-histograms adaptively based on the heat conduction theory. By designing a metric called AHV, the background and non-background sub-histograms are distinguished, and then enhanced separately where more grayscales are allocated to non-background sub-histograms than background sub-histograms.
