Title: Keigo Hashirano: Innovator in Wavelet Transform Technology
Introduction
Keigo Hashirano is a notable inventor based in Kanagawa, Japan. He has made significant contributions to the field of wavelet transform technology, holding 2 patents that showcase his innovative approach to image processing.
Latest Patents
One of his latest patents is the "Five-by-three wavelet transform apparatus." This apparatus includes a function-A module that calculates equations A1 and A2, a function-B module for equations B1 and B2, a function-C0 module for equation C0, and a function-C1 module for equation C1. The selectors are configured to '1' for a forward transform and '0' for an inverse transform. The equations A1 and B1 are utilized for reversible transforms, while A2 and B2 are for irreversible transforms. The equations are defined as follows: out=RoundOff {(in0+in1+0×2000)≫2}. A1out=0.25*(in0+in1). A2out=RoundOff(in0+in1). B1out=0.5*(in0+in1). B20out=0in0+1in1. C01out=0in0−1in1. C1.
Another significant patent is the "Two-dimensional subband coding equipment." This invention features a two-dimensional wavelet transformer that includes a vertical wavelet transform block and a horizontal wavelet transform block. The vertical wavelet transform block processes original image data P, outputting a data string of vertical low-frequency band coefficients (L coefficients) and high-frequency band coefficients (H coefficients) sequentially. The horizontal wavelet transform block then transforms these coefficients alternately, allowing for efficient processing with reduced memory capacity and time.
