Title: Lina J Karam: Innovator in Video Signal Transmission and Image Compression
Introduction
Lina J Karam is a prominent inventor based in Phoenix, AZ (US). She has made significant contributions to the fields of video signal transmission and image compression. With a total of 3 patents, her work has had a substantial impact on communication technologies.
Latest Patents
One of her latest patents is a system and method for the transmission of video signals using multiple channels. This innovative approach facilitates the transmission of video frames over multiple low-data-rate channels. The system includes a video encoder/decoder that generates frame data for each video frame, transforming it to obtain transform coefficients. These coefficients are assembled into quadtrees and coded separately. Additionally, motion vectors are split into coding blocks and coded independently. This method ensures error-resilient reception of transform coefficient packets and motion vector packets, allowing for the reconstruction of received video frames even in the event of data loss.
Another notable patent involves the compression of color images based on a two-dimensional discrete wavelet transform. This method splits raw image data into multiple channels, including color plane difference channels, and compresses each channel separately. The compression utilizes quantization, resulting in a perceptually lossless image. The method operates directly on images in their Bayer pattern form, with quantization thresholds varying based on the channel and DWT sub-band being processed.
