Encoding a Block of Pixels - A simplified explanation of the abstract
This abstract first appeared for US patent application 18587868 titled 'Encoding a Block of Pixels
The patent application describes methods and encoding units for compressing a block of pixels into a data structure using Haar coefficients, exponent bits, sign bits, and sum bits.
- Haar coefficients are determined for the block of pixels, including differential coefficients and a sum coefficient.
- Exponent bits are determined to represent exponents for the differential coefficients.
- Sign bits are determined to represent signs for the differential coefficients.
- Sum bits are determined to represent the sum coefficient.
- The exponent bits are packed into the first portion of the compressed data structure, the sign bits into the second portion, and the sum bits into the third portion.
- The compressed data structure is then stored.
Potential Applications: - Image and video compression technologies - Data storage and transmission systems - Computer graphics and visual processing applications
Problems Solved: - Efficient compression of pixel data - Reduction of storage space required for image and video files - Faster data transmission rates for visual content
Benefits: - Improved storage efficiency - Faster data transfer speeds - Enhanced visual quality in compressed images and videos
Commercial Applications: Title: "Advanced Image Compression Technology for Enhanced Data Storage" This technology can be utilized in various industries such as: - Media and entertainment - Surveillance and security - Medical imaging - Virtual reality and augmented reality
Questions about Image Compression Technology: 1. How does this technology compare to existing image compression methods? This technology offers improved compression efficiency and faster data transfer rates compared to traditional methods.

Original Abstract Submitted
Methods and encoding units for encoding a block of pixels into a compressed data structure. A set of Haar coefficients is determined for the block of pixels, including differential coefficients and a sum coefficient. A set of exponent bits is determined representing exponents for the differential coefficients. A set of sign bits is determined representing signs for the differential coefficients. A set of sum bits is determined representing the sum coefficient. The determined set of exponent bits is packed into a first portion of the compressed data structure; the determined set of sign bits is packed into a second portion of the compressed data structure; and the determined set of sum bits is packed into a third portion of the compressed data structure. The compressed data structure is stored.
