Spacetodepth block
Web深度からのデータを空間データのブロックに並べ替えます。 これはSpaceToDepthの逆変換である。 具体的には、この演算は、 depth 次元の値を空間ブロックとして height 次元と width 次元に移動させた入力テンソルのコピーを出力する。 attr block_size は、入力ブロックサイズとデータの移動方法を示す。 深さからサイズ block_size*block_size のデー … WebY = spaceToDepth(X,blockSize) rearranges spatial blocks of the formatted dlarray object, X, along the depth dimension.The blocks of data have size blockSize. Given an input feature map of size [H W C] and blocks of size [height width], the output feature map size is [floor(H/height) floor(W/width) C*height*width].

Web6. mar 2024 · space_to_depth is a convolutional practice used very often for lossless spatial dimensionality reduction. Applied to tensor (example_dim, width, height, channels) with block_size = k it produces a tensor with shape (example_dim, width / block_size, height / block_size, channels * block_size ** 2). WebSpaceToDepth rearranges blocks of spatial data into depth. More specifically, this op outputs a copy of the input tensor where values from the height and width dimensions are moved to the depth dimension. Attributes. blocksize (required): Blocks of [blocksize, blocksize] are moved.
