According to the embodiments of the present disclosure, there is provided a method for detecting feature points in an image. The method comprises: processing data of the image using a first type of convolutional layers in a Convolutional Neural Network (CNN) to generate first processed data, wherein the first type of convolutional layers comprise convolution kernels having non-shared weights; processing the first processed data using a second type of convolutional layers in the CNN to generate second processed data, wherein the second type of convolutional layers comprise convolution kernels having shared weights; and determining the feature points in the image based on the second processed data. In addition, the embodiments of the present disclosure further provide a corresponding device and a corresponding computer readable storage medium.
