Web11. apr 2024 · In order to extract the saliency features of the panoramic image more effectively, some scholars have proposed convolution methods suitable for the spherical domain [ 6 ]. These methods deploy the SO (3) group correlation in the upper layer of the spherical CNN, where the convolution kernel is defined in the spherical domain. WebA spherical image is an image O depicting the visual information converging to a point o. More concretely, this visual information is represented on a unitary sphere centered at o. A value , i.e., the visual information at position , corresponds to the color of a point positioned on the line spanned by o and .
