This study proposes a technique to generate effective features to classify fundamental human body postures in image sequences such as standing, sitting on the chair, sitting on the floor, bending, and lying down. Truncated discrete cosine transform (DCT) is utilized to obtain features before performing truncated singular value decomposition (SVD). It has been shown that the truncated DCT disregards unnecessary values and thus makes features more simple and light, resulting in an improvement in classification speed. Moreover, this study verifies that the newly extracted features contribute to an increase in the accuracy of the human posture classification, and a definite decrease in distinction errors for bending and sitting postures.
