To observe the clinical efficacy of warm needling therapy for chronic lumbar strain. A total of 60 patients with chronic lumbar strain who met the inclusion criteria were randomized into a treatment group and a control group by the random number table, with 30 cases in each group. The treatment group was treated with warm needling therapy, while the control group was treated with ordinary acupuncture treatment. The treatments were both performed once every other day, and 7 times constituted a course of treatment. Visual analog scale (VAS) score was used to assess the degree of pain and the clinical efficacy was compared between the two groups. The total effective rate of the treatment group was higher than that of the control group (P 0.05). After treatment, the VAS scores of both groups decreased significantly, and the intra-group differences were statistically significant (both P

In this paper, we present an algorithm for segmenting moving objects from videos based on lifting wavelet transform. We firstly segment a video into scenes. Then several iteration of 1D lifting wavelet transforms are performed on each scene on time axis. Because wavelets have the ability of telling apart different frequency, we can extract the sections with high frequency, which represent the moving objects in a video. At last, through binarization and morphologic processing, the moving objects are completely segmented out. Experiments on videos show that our algorithm is very fast and feasible.
