Mean Shift Tracking with Advanced Background-Weighted Histogram

Applied Mechanics and Materials, 2013
Tracking objects in videos using mean shift technique has brought to public attention. In background-weighted histogram (BWH) algorithm proposed by Kernel-Based Object tracking attempts to reduce the interference of background target localization in mean shift tracking.

On the Security of Reversible Data Hiding Based-on Histogram Shift

2008 3rd International Conference on Innovative Computing Information and Control, 2008
Recently, Hwang et al. (HKC) proposed a simple improvement reversible data hiding scheme based on the histogram shift. They claim that the read don't send any additional information to the receiver in their scheme. However, it will generate an informal distribution in the histogram when the secret data is embedded into a cover image.

Fast Density Estimation from Histograms in Shift Invariant Spaces

Sampling Theory in Signal and Image Processing, 2004
Histograms are mostly used as data presentation. In many applications we are interested in a good approximation of the density function, which creates the histograms. Standard techniques like the kernel density estimation are applied for approximating the density function. The problem of these techniques is that the data which define the histogram need

On Frequency Polygons and Average Shifted Histograms in Higher Dimensions

1986
Abstract : Scott has recently studied two simple variations on the ordinary histogram, namely the frequency polygon and the average shifted histogram, and found that they are able to compete with for example kernel density estimators in performance while retaining the advantage of being conceptually and computationally simple.
