PARTIAL EIGENVALUE DECOMPOSITION OF LARGE IMAGES USING SPATIAL-TEMPORAL ADAPTIVE METHOD

Finding eigenvectors of a sequence of real images has usually been con sidered to require too much computation to be practical. Our spatial t emporal adaptive (STA) method reduces the computational complexity of the approximate partial eigenvalue decomposition based on image encodi ng, Spatial temporal encoding is used to reduce storage and computatio n, and then, singular value decomposition (SVD) is applied. After the adaptive discrete cosine transform (DCT) encoding, blocks that are sim ilar in consecutive images are consolidated. The computational economy of our method was verified by tests on different large sets of images , The results show that this method is 6 to 10 times faster than the t raditional SVD method for several kinds of real images, The economy of this algorithm increases with increasing correlation within the image and with increasing correlation between consecutive images within a s et, This algorithm is useful for pattern recognition using eigenvector s, which is a research field that has been active recently.
