3. The method of claim 1 , wherein saliency detection comprises: applying a discrete cosine transform (DCT) on the segmented likely logo regions of an image in a selected video frame to determine spectral saliency of each likely logo region; and measuring multi-scale similarity at two higher scales and a smaller scale of the spectral saliency of each likely logo region.

The method of claim 1 , wherein saliency detection comprises: applying a discrete cosine transform (DCT) on the segmented likely logo regions of an image in a selected video frame to determine spectral saliency of each likely logo region; and measuring multi-scale similarity at two higher scales and a smaller scale of the spectral saliency of each likely logo region. 4. The method of claim 3 , wherein the multi-scale similarity measures include orientation gradient histograms, hue, saturation, value (HSV) histograms, and stroke width transform (SWT) statistics which include total number of strokes, number of horizontal strokes, number of vertical strokes, stroke density, and number of loops.
