Webnormalization constant this Gaussian kernel is a normalized kernel, i.e. its integral over its full domain is unity for every s . This means that increasing the s of the kernel reduces the amplitude substantially. Let us look at the graphs of the normalized kernels for s= 0.3, s= 1 and s= 2 plotted on the same axes: Unprotect@ gaussD ;gauss@ x ... WebLearning Spherical Convolution for Fast Features from 360° Imagery We propose a generic approach that can transfer Convolutional Nerual Networks that has been trained on perspective images to 360° images. Our solution entails a new form of distillation across camera projection models.
