Title: Innovations by Karthikeyan Kannappan

Introduction

Karthikeyan Kannappan is an accomplished inventor based in San Jose, CA. He has made significant contributions to the field of image processing, particularly through his innovative patents. With a total of 2 patents, his work focuses on enhancing the efficiency of affine transformations in images.

Latest Patents

Karthikeyan's latest patents include an "Apparatus for 2-D affine transformation of images" and a "Method for 2-D affine transformation of images." Both patents describe a process where affine image transformations are performed in an interleaved manner. This involves alternating coordinate transformations and intensity calculations incrementally on small portions of an image. The processing of pixels occurs in rows, allowing for efficient reference and transformation of coordinates. After the coordinate transformation, which can include translation, rotation, skew, and scaling, intermediate metapixels are adjusted to eliminate any holes and overlaps. The intensity values of the output metapixels are calculated based on the sum of scaled portions of the intermediate metapixels that cover the output pixels.
