1. An image search method, which retrieves at least one relevant image from a plurality of candidate images via computerized calculations, wherein each said candidate image has at least one candidate object, and each said candidate object has a plurality of candidate-object feature parameters, comprising the following steps: a. providing an image query interface, wherein said image query interface presents p sample images, and a user selects q target feature points from said p sample images, where p≧1, and q≧1; b. locating q corresponding target objects from said p sample images according to said q target feature points, wherein each of said q target objects has a plurality of target-object feature parameters; c. performing similarity calculations between said q target objects and said plurality of said candidate images to retrieve images relevant to said q target objects, wherein each said candidate image has at least one candidate object, and said candidate object has a plurality of candidate-object feature parameters that cooperate with said target-object feature parameters of said q target objects to implement said similarity calculations; and d. arranging said candidate images in sequence according to values obtained in said similarity calculations and outputting said candidate images having been arranged in sequence.
