A Transformed Domain based Novel Focus Measure for 3D Shape Recovery
TL;DR: Wang et al. as discussed by the authors introduced a novel focus measure for Shape From Focus (SFF) based on 1-dimensional Discrete Cosine Transform (DCT) instead of locally computing the focus quality in a window, they constructed a vector consisting of seven pixels for each pixel in the image volume.
Journal ArticleDOI
SSMD-UNet: semi-supervised multi-task decoders network for diabetic retinopathy segmentation
TL;DR: In this paper , a semi-supervised multitask learning approach was proposed for diabetic retinopathy (DR) segmentation using unlabeled data (i.e., Kaggle-EyePACS) to improve DR segmentation performance.
Book ChapterDOI
Using multi level nearest neighbor classifiers for G-protein coupled receptor sub-families prediction
TL;DR: This study makes use of the hydrophobicity of the proteins in order to obtain a fourier spectrum of the protein sequence, which is then used for classification purpose and results are formulated using three performance measures, the Mathew's Correlation Coefficient (MCC), overall accuracy (ACC) and reliability (R).
Proceedings ArticleDOI
Channel boosting based detection and segmentation for cancer analysis in histopathological images.
TL;DR: In this article , the Pyramid Vision Transformer Channel Boosted Lymphocyte Detection (PVTCB-Lymph-Det) is proposed for lymphocyte detection. And the proposed network is based on a transformer and Convolutional Block Attention Mechanism (CBAM) with ResNet-50 to perform feature extraction.
Journal ArticleDOI
A survey of the Vision Transformers and its CNN-Transformer based Variants
TL;DR: In this article , the authors present a taxonomy of the recent vision transformer architectures, and more specifically that of the hybrid vision transformers, highlighting the potential of these architectures to achieve outstanding performance on a variety of computer vision tasks.
