Document Type and Number:
WIPO Patent Application WO/2019/033683
Kind Code:
A1
Abstract:
An image processing method, comprising: reading from an external memory a first part of image data from among image data requiring processing; caching the first part of image data into a first internal memory, and performing image scaling processing on the first part of image data to obtain first scaling image data; caching the first scaling image data into a second internal memory, and performing gradient calculation on the first scaling image data to obtain first gradient image data; caching the first gradient image data into a third internal memory, and performing characteristic vector extraction on the first gradient image data to obtain a first image characteristic value; storing the first image characteristic value in the external memory. Further provided by the present invention are an image processing apparatus and an electronic device. The present invention may increase the speed of extracting characteristic values and reduce the bandwidth usage of an external memory.
