Title: Innovations of John F Hughes

Introduction

John F Hughes is a notable inventor based in Barrington, Rhode Island. He has made significant contributions to the field of technology, particularly in image processing and 3D modeling. With a total of 2 patents, Hughes continues to push the boundaries of innovation.

Latest Patents

Hughes' latest patents include a "System and method for image matting." This method compresses a set of correlated signals by first converting each signal to a sequence of integers, which are further organized as a set of bit-planes. An inverse accumulator is applied to each bit-plane to produce a bit-plane of shifted bits, which are permuted according to a predetermined permutation to produce bit-planes of permuted bits. Each bit-plane of permuted bits is partitioned into a set of blocks of bits. Syndrome bits are generated for each block of bits according to a rate-adaptive base code. Subsequently, the syndrome bits are decompressed in a decoder to recover the original correlated signals. Another significant patent is for "Free-form modeling of objects with variational implicit surfaces." In this invention, an input device is used to generate input strokes on a display device. The input strokes are acquired and resampled to be evenly spaced. Depth values are assigned to the resampled 2D points to form 3D contours. Variational implicit surfaces are fitted to the 3D contours to generate 3D blobs forming the 3D model to be rendered on an output device. The blobs can be merged by guidance strokes and modified by target strokes.
