Title:
IMAGE FEATURE EXTRACTION METHOD, APPARATUS AND DEVICE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/148071
Kind Code:
A1
Abstract:
An image feature extraction method, apparatus and device, and a storage medium. The steps of the method comprise: acquiring parameters to be quantized of a network layer in a neural network model (S101); determining whether values of said parameters are all positive number (S102); if the values of said parameters are all positive numbers, performing a quantization operation on said parameters on the basis of an asymmetric linear quantization logic (S103); if the values of said parameters are not all positive numbers, performing a quantization operation on said parameters on the basis of a symmetric linear quantization logic (S104); and performing feature extraction on an inputted picture by using the neural network model on which the quantization operation has been performed (S105). Said method increases the efficiency of a neural network model extracting picture features while ensuring the precision of the neural network model extracting picture features.
