``Smart Bloodstain Analysis: AI vs Human Expertise``

``Bloodstain pattern analysis (BPA) can be quite complex due to the similarities between impact spatters and fly spots. Expertise is currently the gold standard, but it has its drawbacks such as low efficiency, high error rates, and vulnerability to external factors. To improve this process, researchers turned to AI and transferred learning techniques. They used two types of bloodstains from simulation experiments and a pre-trained model called ResNet-18 for feature extraction.By tweaking the fully connected layer, they increased the model's capability to differentiate between bloodstains. The result? A 93% accuracy rate! This breakthrough aims to assist investigators and BPA analysts in quickly and accurately identifying bloodstains, which can be crucial for reconstructing crime scenes and making BPA smarter. ``
