The Quality Detection Method of Connectors Based on Region Form Characteristics

Considering in the progress of the power quality detection for disturbance signal, detected signals are often has the problem of random noise and impulse noise, in this paper, by using traditional wavelet de-noising, put forward a detection method of disturbance signal based on mathematical morphology and lifting wavelet, discussed its detection principle and implementation methods. Simulation results show that the method de-noising effect is obvious, can effectively improve the accuracy of the disturbance signal judgment.

with the rapid development of digital printing, the method and standard of quality detection for digital printing become focus of research. The main work and innovations in this paper include: ①Computer image analysis method was applied to ink-jet printing quality detection for the first time; ②Compared with traditional printing quality test, ink dot, line, color patch and MTF (Modulation Transfer Function) were selected as measurement and control elements. And the test proofs for detecting printing quality were designed; ③The detection algorithm and the overall detection process were put forward in this paper. The result of the experiment demonstrates: the detection method based on capturing measurement and control elements by CCD can accurately accomplish the objective quality evaluation for ink-jet printing. Detection method of print was improved to extend the scope of detection by this research, which could be generalized as a standard method for the detection of ink-jet printing quality.
