Webb1 jan. 2014 · In this paper, we propose an algorithm to reversibly embed secret data directly in encrypted H.264/AVC stream. The encrypted H.264/AVC streams are obtained by encrypting the IPM, MVD, and DCT coefficients’ signs with a stream cipher. Reversible data hiding in encrypted domain is then performed based on histogram-shifting of … WebbHow to read the histogram. The histogram indicates darker values toward the left and brighter values toward the right. The histogram changes depending on the exposure compensation. A peak at the right or left end of the histogram indicates that the image has an overexposed or underexposed area, respectively.

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. kitchen story berkeleyWebb1 jan. 2024 · Then, some secret data, which is used to manage encrypted images, is embedded into the largest and smallest pixels in non-overflow blocks by utilizing pixel-value-ordering and histogram shifting techniques.
