Channel-wise conv
WebConvolve each channel with an individual depthwise kernel with depth_multiplier output channels. Concatenate the convolved outputs along the channels axis. Unlike a regular 2D convolution, depthwise convolution does not mix information across different input channels. WebDepthwise Convolution is a type of convolution where we apply a single convolutional filter for each input channel. In the regular 2D convolution performed over multiple input channels, the filter is as deep as the input and lets us freely mix channels to generate each element in the output. In contrast, depthwise convolutions keep each channel separate. …

WebFor channel-wise separable (also known as depth-wise separable) convolution, use grouped convolution with number of groups equal to the number of channels. Tip The function, by default, convolves over up to three dimensions of X labeled "S" (spatial).

The only thing that is lacking is a clear understanding of where you want the transformation data to be re-used, if at all. My current understanding is that you want it to be re-used channel-wise.
WebDec 5, 2024 · In a color image, we normally have 3 channels: red, green and blue; this way, a color image can be represented as a matrix of dimensions w × h × c, where c is the number of channels, that is, 3. A convolution layer receives the image ( w × h × c) as input, and generates as output an activation map of dimensions w ′ × h ′ × c ′.
