Title: Innovations of Daniel Gnanaprakasam

Introduction

Daniel Gnanaprakasam is an accomplished inventor based in Secane, PA (US). He has made significant contributions to the field of image processing, holding a total of 2 patents. His work focuses on advanced techniques for image compression and edge detection, which have practical applications in various digital imaging technologies.

Latest Patents

One of his latest patents is a "Segmentation based image compression system." This innovative system encodes a natural image into a segmented or mosaic image that features well-defined edges and a residual image. The segmented image is encoded using a lossless encoding technique, while the residual image is encoded using a lossy technique. This encoded image can be recorded on a video tape, allowing the segmented image to be recovered in picture-in-shuttle modes such as fast forward and fast rewind. The system employs a multi-scale edge finder that resolves transitions occurring over two, four, and eight pixels into an edge located between two pixels. Additionally, the lossless encoder includes circuitry that chain-encodes the segmented image into a low-resolution image and multiple complementary images, enabling efficient storage and recovery.

Another notable patent is the "Image edge finder which operates over multiple picture element ranges." This edge finder locates edges in a digitized image across various pixel value ranges. It assigns an edge characteristic value to each pixel, representing a minimum edge value for that pixel in the image. The edge finder can resolve transitions between two pixels or over groups of four or eight pixels, determining whether an edge should be defined. It simultaneously examines four edges in two dimensions to ascertain the edgeness value for each pixel in the digitized image.
