Concept¶
Image Convolution¶
Weighting Sharing¶
Pooling¶
- downscale
- small translation-invariance
Downscale¶
- resize
- stride
- pooling
- max pooling
- avg pooling
Stride vs pooling¶
stride | pooling | |
---|---|---|
computation | less | 4 times more computation+pooling operate |
propagation | bad | better |
Upscale / Up-sampling¶
used for 1. reverse downscale, 2. increase resolution
usually required for pix 2 pix application, e.g. segmentation, super-resolution
Methods¶
- resize
resampling and interpolation - deconvolution Deconvnet
- PixelShuffle
