Problems solved by technology

[0003] The existing processing methods mainly have the following two problems: Problem 1: The feature enhancement and compression processing modules are divided into two independent processes and modules, resulting in a large and complex system, low system integration, and slow processing speed
Question 2: The feature enhancement and compression processing modules are divided into two independent processes and modules. The two modules are processed in time-sharing, and there is a sequence. If the data is compressed first and then the feature is enhanced, the enhancement effect is likely to be unsatisfactory; or the feature is enhanced first and then the feature is enhanced. Compression can easily lead to a low compression ratio and weaken the effect of feature enhancement after compression; taking care of one and losing the other will lead to a decline in the final system performance of the system and affect the signal processing effect of subsequent modules

Description

technical field [0001] The invention relates to a signal processing method for feature enhancement and data compression of two-dimensional data arrays, in particular to a method for synchronously performing two-in-one feature enhancement and data compression of two-dimensional data arrays. Background technique [0002] In the signal data processing scheme, it is often necessary to process the two-dimensional signal data in the following ways: Processing method 1: Enhance characteristic parts to highlight specific parts. Processing method 2: reduce the amount of data, save data space and speed up data processing. [0003] The existing processing methods mainly have the following two problems: Problem 1: The feature enhancement and compression processing modules are divided into two independent processes and modules, resulting in a large and complex system, low system integration, and slow processing speed. Question 2: The feature enhancement and compression processing module...
