| Abstract(in English) | Most of constant-time Gaussian filters ($O(1)$ GF) based on the Discrete Cosine Transform (DCT), which provide high performance tradeoff between approximation accuracy and computational complexity, has a general framework that a Gaussian kernel is approximated by few cosine termsand then each cosine term is convolved in a constant-time manner. It is well known that DCT has the eight types of definitions but, for $O(1)$ GF, all the DCT types have not been studied comprehensively. This comprehensive analysis is important to clarify differences of $O(1)$ GF derived from each DCT. This paper analyses the eight-types of DCT using a general form of them and clarifies their differences for $O(1)$ GF. In addition, this paper derives a moment-preserving Gaussian approximationfor DCT-1,3,5,7 from a viewpoint of convex optimization. |
