The embodiment of the invention discloses an image classification method, a system, a device and a computer readable storage medium. The method comprises the steps of extracting a target feature set of a to-be-classified image, wherein features contained in the target feature set are determined by an optimal feature subset of sample images which are the same as the feature dimension of the to-be-classified image and have the same meaning as features represented by each feature; inputting the target feature set of the to-be-classified image into a support vector machine classifier and obtaininga label type to which the to-be-classified image belongs. The determining process of the optimal feature subset is as follows: calculating the interval of each sample image in a weight space, calculating a feature weight vector according to each interval iteration until an iteration ending condition is met, obtaining the weight value of each feature of each sample image, combining all features according to the weight val
