GroupMixer: Patch-based Group Convolutional Neural Network for Breast Cancer Detection from Histopathological Images

no code implementations16 Nov 2023 Ardavan Modarres, Erfan Ebrahim Esfahani, Mahsa Bahrami

In this paper, we borrowed the previously introduced idea of integrating a fully Convolutional Neural Network architecture with Patch Embedding operation and presented an efficient CNN architecture for breast cancer malignancy detection from histopathological images.

Compressed MRI Reconstruction Exploiting a Rotation-Invariant Total Variation Discretization

1 code implementation26 Nov 2019 Erfan Ebrahim Esfahani, Alireza Hosseini

Inspired by the first-order method of Malitsky and Pock, we propose a new variational framework for compressed MR image reconstruction which introduces the application of a rotation-invariant discretization of total variation functional into MR imaging while exploiting BM3D frame as a sparsifying transform.
