==IMAGE DATA DECOMPRESSION - A simplified explanation of the abstract==


This abstract first appeared for US patent application 18532587 titled 'IMAGE DATA DECOMPRESSION

'''Simplified Explanation:'''
The patent application describes a method for determining image element values from compressed data representing a block of image data with multiple channels, including a reference channel and non-reference channels, through decompression.

* Compressed channel data is used to determine initial data values for each image element.
* Decompressed data values for non-reference channels are determined based on compression modes - either channel decorrelating mode or non-channel decorrelating mode.
* If the compression mode is non-channel decorrelating, the decompressed data value for the non-reference channel is the initial data value for that channel.
* If the compression mode is channel decorrelating, the decompressed data value for the non-reference channel is a function of the initial data values for the non-reference channel and one of the reference channels.

'''Key Features and Innovation:'''
* Determining image element values from compressed data with multiple channels.
* Decompressing data to determine initial values for each image element.
* Differentiating between compression modes to determine decompressed data values for non-reference channels.

'''Potential Applications:'''
This technology can be applied in image processing, data compression, and multimedia applications where efficient decompression of image data is required.

'''Problems Solved:'''
This technology addresses the challenge of efficiently determining image element values from compressed data with multiple channels, improving data processing and decompression efficiency.

'''Benefits:'''
* Improved image data decompression efficiency.
* Enhanced image processing capabilities.
* Better utilization of compressed data for image analysis.

'''Commercial Applications:'''
The technology can be utilized in industries such as digital imaging, video processing, medical imaging, and remote sensing for efficient data compression and processing.

'''Prior Art:'''
Readers can explore prior patents related to image data compression, decompression, and channel decorrelation techniques to understand the evolution of this technology.

'''Frequently Updated Research:'''
Researchers are continually exploring advancements in image data compression and decompression techniques, including the optimization of channel decorrelation methods for improved image processing efficiency.

'''Questions about Image Data Decompression:'''
1. How does this technology improve the efficiency of image data decompression?
2. What are the potential applications of this method in multimedia industries?


==Original Abstract Submitted==

Image element values are determined from compressed data representing a block of image data comprising data values relating to a respective plurality of channels including a reference channel and a plurality of non-reference channels by performing decompression. Compressed channel data is read from the compressed data and used to determine an initial data value relating to a channel for each of the image element values being decompressed. For each of the image element values, a decompressed data value is determined for the non-reference channels by: (i) reading, from the compressed data, an indication of a compression mode, wherein the compression mode is either a channel decorrelating mode or a non-channel decorrelating mode, (ii) if the compression mode is the non-channel decorrelating mode, determining the decompressed data value for the non-reference channel to be the determined initial data value relating to the non-reference channel for the image element value; and (iii) if the compression mode is the channel decorrelating mode, determining the decompressed data value for the non-reference channel to be a function of the determined initial data value relating to the non-reference channel and the determined initial data value relating to one of the reference channels for the image element value.
