Histogram shifting

WebbThe cumulative histogram is a special histogram that can be derived from the normal histogram. We find the counts of each intensity value from 0–255 and then add each subsequent counts, if i = 0 then H(i) = h(0) else H(i) = H(i-1) + h(0) Cumulative histograms are useful in many image processing applications like histogram equalization and so on. WebbHistogram shifting is adopted, which adds watermark to differences or shifts difference histogram according to the occurrences of differences. Due to the application of pre-processing, after watermark embedding, the right pixel of the watermarked pair is …

Mean shift - Wikipedia

WebbMean shift is an application-independent tool suitable for real data analysis. Does not assume any predefined shape on data clusters. It is capable of handling arbitrary feature spaces. The procedure relies on choice of a single parameter: bandwidth. The bandwidth/window size 'h' has a physical meaning, unlike k -means. Webb24 mars 2024 · Histogram shifting is one of the most popular techniques for achieving reversible data hiding technology. However, invalid shifting in histogram shifting limits the performance of existing reversible data hiding schemes.
