These high-resolution images have been used in several domains. Diabetic retinopathy (DR) is a medical condition where increased blood sugar levels of diabetic patients affect the retinal vessels of the eye. The usage of high-resolution fundus images in DR classification is quite limited due to Graphics processing unit (GPU) memory constraints. The GPU memory problem becomes even worse with the increased complexity of the current state-of-the-art deep learning models. In this paper, we propose a memory-efficient divide-and-conquer-based approach for training deep learning models that can identify both high-level and detailed low-level features from high-resolution images within given GPU memory constraints. The proposed approach initially uses the traditional transfer learning technique to train the deep learning model with reduced-sized images. This trained model is used to extract detailed low-level features from fixed-size patches of higher-resolution fundus images. These detailed features are then utilized for classification based on standard machine learning algorithms. We have evaluated our proposed approach using the DDR and APTOS datasets. The results of our approach are compared with different approaches, and our model achieves a maximum classification accuracy of 95.92% and 97.39% on the DDR and APTOS datasets, respectively.

Therefore, we need new, more effective models and tools to tackle current problems quickly. The main objective of the work is to improve the 3D ResNet50 model for skin cancer classification by transfer learning. Trained on the ISIC 2024 3D Total Body Photographs (3D-TBP), a Kaggle competition dataset, the model aims to detect five significant types of skin cancer: Melanoma (Mel), Melanocytic nevus (Nev), Basal cell carcinoma (BCC), Actinic keratosis (AK), and Benign keratosis (BK). While fine-tuning achieves peak performance, data augmentation addresses the issue of overfitting. The proposed model outperforms state-of-the-art methods with an overall accuracy of 93.88%. Since the accuracy drops to 85.67% while utilizing 2D data, the substantial contribution becomes apparent when working with 3D data. The model articulates excellent memory and precision with remarkable accuracy. According to the findings, the 3D ResNet50 model improves the diagnostic process and may be rated better than conventional approaches as a noninvasive, accurate, and efficient substitute.

This study evaluates the necessity of specific TEs for QSM MRI in ICH patients and identifies shorter scan protocols using computer vision metrics (CVMs) to maintain diagnostic accuracy. Fifty-four patients with suspected ICH were retrospectively recruited. multiecho gradient recalled echo (mGRE) sequences with 11 TEs were used for QSM MRI (reference). Subsets of TEs compatible with producing QSM MRI images were generated, producing 71 subgroups per patient. QSM images from each subgroup were compared to reference images using 14 CVMs. Linear regression and Wilcoxon signed-rank tests identified optimal subgroups minimizing scan time while preserving image quality as part of the computer vision optimized rapid imaging (CORI) method described. CVM-based analysis demonstrated Subgroup 1 (TE1-3) to be optimal using several CVMs, supporting a reduction in scan time from 4.5 to 1.23 min (73% reduction). Other CVMs suggested longer maximum TE subgroups as optimal, achieving scan time reductions of 9%–37%.

Specifically, we design a Multi-scale Convolution Modulation (MCM) module to simplify the self-attention mechanism through a convolution modulation strategy that incorporates multi-scale large-kernel convolution into depth-separable convolution, effectively extracting the multi-scale global features and local features. Besides, we adopt the concept of feature complementarity to facilitate the interaction between high-level semantic features and low-level spatial features through the designed Scale Inter-active Attention (SIA) module.

The challenge is how to improve the segmentation of 3D microscopic images using known segmentation methods, but without losing processing speed. In the first phase of this research, a model was developed based on an ensemble of 11 segmentation methods whose parameters were optimized using genetic algorithms (GA). Optimization of the ensemble of segmentation methods using GA produces a set of segmenters that are further evaluated using a two-stage voting system, with the aim of finding the best segmenter configuration according to multiple criteria. In the second phase of this research, the final segmenter model is developed as a result of two-level optimization. The best obtained segmenter does not affect the speed of image processing in the exploitation process as its operating speed is practically equal to the processing speed of the basic segmentation method. Objective selection and fine-tuning of the segmenter was done using multiple segmentation methods. Each of these methods has been subject to an intensive process of a significant number of two-stage optimization cycles. The metric has been specifically created for objective analysis of segmenter performance and was used as a fitness function during GA optimization and result validation.

To this end, this paper proposes a lightweight convolutional neural network, HSCFNet, for classifying 9 mainstream infectious skin diseases and 10 non-infectious skin diseases. HSCFNet consists of two core modules, the multi-gate hybrid convolution module (MGHC) and triple residual fusion module (TRF). MGHC integrates standard convolution and improved deformable convolution to form two branches and selects different branches for feature extraction through parameter control, while introducing a gating mechanism for feature selection of the extracted features to strengthen the ability of extracting important features. The TRF module facilitates the information interaction between features by fusing three different resolutions of features, which further improves the classification performance of the model. The experimental results show that the accuracy, precision, recall, specificity, and F1 score of HSCFNet reach 97.87%, 97.76%, 97.26%, 99.88%, and 97.43%, respectively, and the size of the model is only 26.1 MB, which is lightweight while maintaining high performance.
