Recently, deep models have been very popular because they achieve excellent performance with many classification problems. Deep networks high computational complexities and require specific hardware. To overcome this problem (without decreasing ability), a hand-modeled feature selection method is proposed in paper. A new shape-based local extractor presented which uses the geometric shape of frustum. By using frustum pattern, textural features are generated. Moreover, statistical extracted...

Abstract Background The aim of this study is to histologically and biomechanically investigate the effects local PRP ozone therapy (O 2 O 3 ) on tendon-to-bone healing in a rabbit model supraspinatus tendon tear. Methods Four groups were formed have seven rabbits each group: repair, R; repair + PRP, RP; ozone, RO; RPO. was detached by sharp dissection from footprint an acute tear pattern created. Thereafter, performed with transosseous technique. In RP group, RPO O2O3 mixture injected site....

We intended to compare the doctors with a convolutional neural network (CNN) that we had trained using our own unique method for Lateral Pillar Classification (LPC) of Legg-Calve-Perthes Disease (LCPD). Thousands training data sets are frequently required artificial intelligence (AI) applications in medicine. Since did not have enough real patient radiographs train CNN, devised novel obtain them. CNN model created by modifying normal hip radiographs. No were ever used during phase. tested on...
