Latest Patents

One of his latest patents is a segmentation-based image compression system. This system encodes a natural image into a segmented or mosaic image with 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. Additionally, the recorded image can be decoded and re-encoded through several generational levels without significant degradation in perceived image quality. The segmented image is produced by an encoder that employs a multi-scale edge finder, capable of resolving transitions occurring over two, four, and eight pixels into an edge located between two pixels. Furthermore, the lossless encoder includes circuitry that chain-encodes the segmented image into a low-resolution image and multiple complementary images, enabling the low-resolution image to be stored as a single data packet and recovered as a unit from the tape in picture-in-shuttle mode.

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