Variable block size lapped transforms
نویسندگان
چکیده
A structure for implementing lapped transforms with time-varying block sizes is presented which allows full orthogonality of the transient transforms. The formulation is based on a factorization of the transfer matrix into orthogonal factors. Such an approach can be viewed as a sequence of stages with variableblock-size transforms separated by sample-shu ing (delay) stages. Details and design examples for a rst order system are presented.

VARIABLE BLOCK SIZE LAPPED TRANSFORMS - Image Processing, 1995. Proceedings., International Conference on
A structure for implementing lapped transforms with time-varying block sizes is discussed. It allows full orthogonality in the transitions based on a factorization of the transfer matrix into orthogonal factors. Such an approach can be viewed as a sequence of stages with variable-block-size transforms intermediated by sampleshuffling (delay) stages. Details for a first order system are given an...

متن کاملLapped Transforms for Image Compression
This chapter covers the basic aspects of lapped transforms and their applications to image compression. It is a subject that has been extensively studied mainly because lapped transforms are closely related to lter banks, wavelets, and time-frequency transformations. Some of these topics are also covered in other chapters in this book. In any case it is certainly impractical to reference all th...
متن کاملGeneralized Linear-Phase Lapped Orthogonal Transforms
The general factorization of a linear-phase paraunitary filter bank (LPPUFB) is revisited and we introduce a class of lapped orthogonal transforms with extended overlap (GenLOT). In this formulation, the discrete cosine transform (DCT) is the order-l GenLOT, the lapped orthogonal transform is the order-:! GenLOT, and so on, for any filter length which is an integer multiple of the block size. A...
متن کاملThe GenLOT: generalized linear-phase lapped orthogonal transform
The general factorization of a linear-phase paraunitary filter bank (LPPUFB) is revisited. From this new perspective, a class of lapped orthogonal transforms with extended overlap (generalized linear-phase lapped orthogonal transforms (GenLOT’s)) is developed as a subclass of the general class of LPPUFB. In this formulation, the discrete cosine transform (DCT) is the order-1 GenLOT, the lapped ...
