Real space transformations of 2D/3D images in PyTorch - teamtomo/torch-transform-image ...

Non-autoregressive Transformer (NAT) is an efficient type of image synthesis model. However, their performance is generally inferior to state-of-the-art image generation models (e.g. diffusion models) ...

This paper presents a pansharpening technique based on the non-subsampled contourlet transform (NSCT) and convolutional autoencoder (CAE). NSCT is exceptionally proficient at presenting orientation ...

First, the intensity-hue-saturation (IHS) of a SPECT and CT image are decomposed using a non-subsampled contourlet transform (NSCT) independently, where both low-frequency and high-frequency images, ...

The reconstructed image is obtained by taking Inverse Non-Subsampled Contourlet Transform (INSCT) on fused subbands. The experimental results on six pairs of medical images are compared in terms of ...
