Bone Fracture Detection Using Hybrid EfficientNet-B0 and ResNet50 with SVM: A Comparative Performance Analysis

Jul 31, 2025

The accurate identification of osseous fractures is crucial for precise medical diagnoses and treatment planning. This study introduces a new hybrid classification approach, integrating EfficientNet-B0 and ResNet50 deep learning models with an SVM classifier, surpassing traditional versions. Leveraging pre-trained feature extractors for EfficientNet-B0 and ResNet50, the proposed method achieves a test accuracy of 98.01% and a recall of 0.99 for fractured cases with EfficientNet-B0+SVM, while reducing runtime to 20.44 minutes. ResNet50 + SVM also improved accuracy from 80.05% to 96.41% with a runtime of 38.47 minutes, compared to 83.96 minutes standalone. This hybrid approach demonstrates significant enhancements in accuracy and efficiency, positioning it as a promising tool for clinical bone fracture detection. ©2025 The authors.

FPGA based Fuzzy Edge Detection System for COVID-19 X-Ray Images

Apr 30, 2025

COVID-19 pandemic has caused a global crisis, with widespread loss of life and severe health issues, including lungs damage. COVID-19 diagnosis typically obtains by either chest X-ray images, which require a precise diagnosis, or a polymerase chain reaction test, which needs long-time. Rapid and precise diagnosis is crucial for preserving lives. This study aims to present an efficiently and accurately system that is capable to identify edges in X-ray images, allowing prompt and precise diagnosis. The fuzzy image processing methods is utilized in MATLAB to identify edges of the images. This stage is performed for verification purposes and to compare the findings with hardware platform outcomes. The hardware platform is implemented by High-Level Synthesis technology as a software-platform and the ZYNQ-7000 kit as a hardware-platform. Software and hardware platforms combination produce precise edges and faster processing time compared with the results obtained by MATLAB. Higher degree of similarity between the two proposed approaches for healthy images (87%-98.8%) compared to those for infected images (80%-98.2%) have been obtained. Significant contribution of this study is the inclusion of the PS component on the ZC702 board which enabled the use of floating-point data representation and allowed for fast implementation with minimal resource usage. ©2025 The authors.
