WebWe propose to learn a spherical convolutional network that translates a planar CNN to process 360 {\deg} imagery directly in its equirectangular projection. Our approach learns to reproduce the flat filter outputs on 360 {\deg} data, sensitive to the varying distortion effects across the viewing sphere. WebOct 7, 2024 · Abstract: Deep Learning techniques like Convolutional Neural Networks (CNN) are getting popular for image classification with broad usage spanning across automotive, industrial, medicine, robotics etc. Typical CNN network consists of multiple layers of 2D convolutions, non-linearity, spatial pooling and fully connected layer, with 2D convolutions …
