Principles of Spatial Filters. For many applications, such as holography, spatial intensity variations in the laser beam are unacceptable. Our KT spatial filter system is ideal for producing a clean Gaussian beam. Figure 1: Spatial Filter System. The input Gaussian beam has spatially varying intensity "noise". On the other hand, for the intra-frame analysis and synthesis, one uses the highly efficient recursive filter banks. The proposed sub-band coding technique uses the base sub-band of the low-temporary subsequence in a simple detector of the scene moving areas. Information in other sub-bands is coded only in the areas related to significant.
