如何评价球面卷积神经网络(Spherical CNNs)? - 知乎
WebOct 27, 2024 · SphereNet的中心思想是将本地CNN操作(例如卷积和池化)从常规图像域提升到表示鱼眼或全向图像的球面,其实现是通过将内核表示为球体相切的小补丁(patch)。. 球体切平面上的目标从不同的高度投影到等矩形图像表示时,卷积核的采样网格位置以相同的 … Web而在2024年的ICLR上,Cohen推出了一篇极具应用潜力的oral paper:球面CNN(Spherical CNN),把卷积网络推广到球面图像的特征提取上,并且巧妙地利用广义傅里叶变换实现快速群卷积(互相关)操作。. 在实验部分,作者维持了一惯的简洁风格,但是引入了一个备受 … WebSpherical CNNs.
