ROI image retrieval based on multiple features of mean shift and expectationmaximisation
An image retrieval by using MS and EM to adaptively change the location and scale of the region of interest (ROI). EM-like merged into the colour and spatial features to detect the scale and position of the ROI. A novel similarity measure based on the colour and spatial histograms over the lattice structure. Huge speed up the EM-like iteration due to the proposed similarity measure.
