| Abstract: | An automatic test system for HDTV mainboard based on LabVIEW is designed to conquer the disadvantages of low efficiency and subjectivity by manual testing. Audio and video quality assessment software has been developed by taking full advantage of the graphical programming of LabVIEW which has abundant signal processing functions and visual instruments. Structural similarity algorithm based on gradient （GSSIM） has been proposed to improve the accuracy of fuzzy images. This system can greatly improve the testing efficiency, and also ensure the objectivities and conformity of different products testing. |
