In order to aid walking and limb rehabilitation training, a four-degree pelvic pose and position control mechanism of walking aid robot is discussed based on the motion laws of human pelvic. By applying modified D-H method, a kinematical coordinate system of the pose and position control mechanism is set up and the forward and inverse kinematics models are also built up. After the design of control...
An improved fourth order nonlinear diffusion filtering method is presented. An edge-detection function is introduced and the new method can adjust the diffusion speed adaptively. Compared to some previous high order filtering, the proposed method can preserve edges while denoising. Experimental results demonstrate the performance of the new fourth order nonlinear diffusion method.
This paper presents an edge-preserving fourth order partial differential equation (PDE) method for image denoising. This method can preserve edges and avoid the staircase effect. The proposed fourth order model contains a function of gradient norm as an edge detector, which controls the diffusion speed according to the local structure of the image and preserves more details. Denoising results are...
Cordyceps militaris, a kind of caterpillar fungus, has therapeutic effects including immunoregulative, anticancer, antibacterial and antifungal effects. Aqueous extraction and alkaline (NaOH) hydrolysis method were comparatively studied in polysaccharides extraction from submerged-cultured C. militaris mycelia. The results indicate that the polysaccharide content and the total extract rate from alkaline...
The color correlogram has proven its worth as an image descriptor for both comparison and retrieval. The paper presents a case study of developing efficient color correlogram algorithms on the STI Cell Broadband Engine (Cell B. E.), which is a state-of-the-art heterogeneous multicore architecture that consists of a traditional microprocessor (PPE) with eight SIMD co-processing unit (SPE) integrated...
