Improved Mean Shift Target Localization using True Background Weighted Histogram and Geometric Centroid Adjustment

Autor: R. Mehmood, N. Huda, J. Song, M. M. Riaz, N. Iqbal, T. S. Choi

Publikováno v: Radioengineering, Vol 25, Iss 3, Pp 612-622 (2016)

Mean Shift (MS) tracking using histogram features alone may cause inaccuracy in target localization. The problem becomes worst due to presence of mingled background features in target model representation. To improve MS target localization problem, t

Noise reduction using mean shift algorithm for estimating 3D shape

Autor: Aamir Saeed Malik, T-S Choi, S-O Shim

Publikováno v: The Imaging Science Journal. 59:267-273

The technique to estimate the three-dimensional (3D) geometry of an object from a sequence of images obtained at different focus settings is called shape from focus (SFF). In SFF, the measure of focus — sharpness — is the crucial part for final 3
