Content-based retrieval of fundus images and diabetic retinopathy detection using variants of local texture features

A Comprehensive Approach to Diabetic Retinopathy Detection: Preprocessing, Segmentation, and Ensemble Learning-Based Grading

This paper presents a multistage computational pipeline for the automated detection and severity grading of diabetic retinopathy (DR) from retinal fundus images, integrating classical image preprocessing, lesion-oriented segmentation, texture-based feature extraction, and ensemble classification into a single reproduci...

A Hybrid Retinal Fundus Image Processing and Neural Network Framework for Diabetic Retinopathy Screening

Diabetic retinopathy (DR) is a retinal disorder that can be screened from fundus photographs using computer-aided image analysis. This paper presents a texture-based framework that combines image preprocessing, Gray-Level Co-occurrence Matrix (GLCM) feature extraction, Principal Component Analysis (PCA), and neural-net...

Hybrid PCA–LBP and Wavelet Scattering Framework for Texture Classification in Color Images

A hybrid framework that integrates Principal Component Analysis, Local Binary Patterns, Wavelet Scattering Transform, and the XGBoost classifier for color texture classification is presented, demonstrating that the two selected complementary feature extraction methods provide a compact yet effective representation for...

Texture classification model based on adaptive local ternary pattern

This research proposes Adaptive Local Ternary Pattern (ALTP) that uses a dynamically calculated threshold to determine texture pattern for an image region that outperformed state-of-the-art texture feature descriptors.

Wavelet Packet-Based Feature Extraction with Multivariate Kernel Sparse Extreme Learning Machine and DenseNet-264 for Diabetic Retinopathy Prediction

Automated Diabetic Retinopathy Severity Grading Using Hybrid Feature Optimization and Weighted Ensemble Learning

Diabetic Retinopathy (DR) is a leading cause of vision loss in individuals with diabetes. It is caused by damage to the retina’s blood vessels, which can result from chronic hyperglycemia. It is crucial to identify signs of DR early and accurately determine severity before treatment can be initiated, as vision loss c...
