In paper Generating High-Quality Crowd Density Maps using Contextual Pyramid CNNs, in Section 3.4, it said




Since, the aim of this work is to estimate high-resolution and
high-quality density maps, F-CNN is constructed using a set of
convolutional and fractionally-strided convolutional layers. The set
of fractionally-strided convolutional layers help us to restore
details in the output density maps. The following structure is used
for F-CNN: CR(64,9)-CR(32,7)- TR(32)-CR(16,5)-TR(16)-C(1,1), where, C
is convolutional layer, R is ReLU layer, T is fractionally-strided
convolution layer and the first number inside every brace indicates
the number of filters while the second number indicates filter size.
Every fractionally-strided convolution layer increases the input
resolution by a factor of 2, thereby ensuring that the output
resolution is the same as that of input.




I would like to know the detail of fractionally-strided convolution layer.

          Here is an animation of fractionally-strided convolution (from this github project):





          where the dashed white cells are zero rows/columns padded between the input cells (blue). These animations are visualizations of the mathematical formulas from the article below:



          A guide to convolution arithmetic for deep learning



          Here is a quote from the article:




          Figure [..] helps understand what fractional strides involve: zeros
          are inserted between input units, which makes the kernel move around
          at a slower pace than with unit strides [footnote: doing so is
          inefficient and real-world implementations avoid useless
          multiplications by zero, but conceptually it is how the transpose of a
          strided convolution can be thought of.]





          Also, here is a post on this site asking "What are deconvolutional layers?" which is the same thing.



          And here are two quotes from a post by Paul-Louis Pröve on different types of convolutions:




          Transposed Convolutions (a.k.a. deconvolutions or fractionally strided
          convolutions)




          and




          Some sources use the name deconvolution, which is inappropriate
          because it’s not a deconvolution [..] An actual deconvolution reverts the process of a convolution.
