Abstract: Implementations of the present specification provide an enhanced training method for an image recognition model. A predetermined quantity or predetermined proportion of samples are randomly selected from a first sample set as a seed sample for extension to obtain several extended samples. The extended sample is obtained by adding disturbance to an original image without changing an annotation result. In a sample extension process, disturbance values are arranged towards neighborhood in predetermined distribution with a reference pixel as a reference, so that real disturbance can be well simulated. Because the annotation result of the extended sample remains unchanged after the disturbance is added, an image recognition model trained by using the extended sample can well recognize a target recognition result of an original image, thereby improving robustness of the image recognition model.
