description This invention provides an image searching method based on feature extraction to determine at least one sample image similar to the image to be searched, including the following steps: a. feature extraction on all sample images to obtain all corresponding feature information, while all sample images are I1, I2, . . . , IS and all said feature information corresponding to all sample images are V1, V2, . . . , VS; b. creating an index tree based on all of said feature information; c. obtaining the feature information corresponding to the image to be searched based on the feature extraction; d. determining said feature information corresponding to at least one sample image having a minimum distance from the image to be searched based on the index tree and the feature information of the image to be searched. The invention has powerful functions and simple operation, and is able to avoid interference of background, text annotation and image merging during processing and filtering of feature extraction, which has good search results and high commercial value.
