Semi-supervised Domain Adaptive Medical Image Segmentation through Consistency Regularized Disentangled Contrastive Learning

1 code implementation6 Jul 2023 Hritam Basak, Zhaozheng Yin

In this work, we investigate relatively less explored semi-supervised domain adaptation (SSDA) for medical image segmentation, where access to a few labeled target samples can improve the adaptation performance substantially.

Pseudo-Label Guided Contrastive Learning for Semi-Supervised Medical Image Segmentation

2 code implementations CVPR 2023 Hritam Basak, Zhaozheng Yin

Although recent works in semi-supervised learning (SemiSL) have accomplished significant success in natural image segmentation, the task of learning discriminative representations from limited annotations has been an open problem in medical images.

IDEAL: Improved DEnse locAL Contrastive Learning for Semi-Supervised Medical Image Segmentation

1 code implementation26 Oct 2022 Hritam Basak, Soumitri Chattopadhyay, Rohit Kundu, Sayan Nag, Rammohan Mallipeddi

To this end, we extend the concept of metric learning to the segmentation task, using a dense (dis)similarity learning for pre-training a deep encoder network, and employing a semi-supervised paradigm to fine-tune for the downstream task.

SVM and ANN based Classification of EMG signals by using PCA and LDA

no code implementations22 Oct 2021 Hritam Basak, Alik Roy, Jeet Bandhu Lahiri, Sayantan Bose, Soumyadeep Patra

One of the main methods used for pattern recognition in myoelectric signals is the Support Vector Machines (SVM) technique whose primary function is to identify an n-dimensional hyperplane to separate a set of input feature points into different classes.

Single Image Super-Resolution using Residual Channel Attention Network

1 code implementation8 Feb 2021 Hritam Basak, Rohit Kundu, Anish Agarwal, Shreya Giri

In this paper, we propose a deep learning-based approach for the problem, wherein we use a fully convolutional attention network coupled with residual in the residual block (RIR), Residual Channel Attention Block (RCAB), and long and short skip connections.

Comparative study of maturation profiles of neural cells in different species with the help of Computer Vision and Deep Learning

1 code implementation7 Feb 2021 Hritam Basak, Rohit Kundu

Our results show different migration patterns between species suggesting different maturation profiles as well as different maturation rates of neuroblast cells in different species.

Optimizing Speech Emotion Recognition using Manta-Ray Based Feature Selection

no code implementations18 Sep 2020 Soham Chattopadhyay, Arijit Dey, Hritam Basak

Recent studies have shown that Mel Frequency Cepstral Coefficients (MFCC) have been emerged as one of the most relied feature extraction methods, though it circumscribes the accuracy of classification with a very small feature dimension.

Multi-scale Attention U-Net (MsAUNet): A Modified U-Net Architecture for Scene Segmentation

no code implementations15 Sep 2020 Soham Chattopadhyay, Hritam Basak

Also, these networks fail to map the long-range dependencies of local features, which results in discriminative feature maps corresponding to each semantic class in the resulting segmented image.
