Feature processing method, feature retrieval method, electronic equipment and computer storage medium

The invention provides a feature processing method based on feature retrieval, a feature retrieval method, electronic equipment and a computer storage medium. The method comprises the steps of obtaining a target feature; according to the feature sample distribution of each feature dimension of the target feature, obtaining a feature sample sorting result, and a segmentation point value and a feature average value of the sorting result; obtaining a first distance between the feature sample and the segmentation point value and a second distance between the feature sample and the feature average value; obtaining the proportion of the feature samples with the second distance smaller than the first distance; quantizing all the feature samples of the feature dimensions of which the feature sample proportions are greater than a preset threshold value according to ternary quantization; quantizing all the feature samples of the feature dimensions of which the feature sample proportions are smaller than or equal to a p
