Based on the comprehensive analysis of the effect of window size on sum of squared differences (SSD) in different cases, according to the property of natural objects and the features of the content of stereo images, a method to adjust window size adaptively is proposed for stereo matching based on object contours and forward prediction.

Based on the comprehensive analysis of the effect of window size on sum of squared differences (SSD) in different cases, according to the property of natural objects and the features of the content of stereo images, a method to adjust window size adaptively is proposed for stereo matching based on object contours and forward prediction. In computer simulations, the processing of one dimension intensity signals reveals clearly that the algorithm can adjust window size quickly and reasonably, and achieve the aim that window size is optimal at almost all pixels. Comparing to those previous adaptive window matching algorithms, this algorithm is simpler.

In Ref.[7] we proved that the energy Lipschitz singularity is quite good for recognition of underwater target. But unfortunately stochastic noise interferes with effective recognition. We propose to use adaptive Gaussian smoothing filter to reduce stochastic noise and in section 1 we discuss theoretically how the singularity feature of the real signal can be enhanced by using adaptive Gaussian smoothing filter. The measured noise signals are the same as used in Ref.[7]. There were 560 samples; the samples for...

In Ref.[7] we proved that the energy Lipschitz singularity is quite good for recognition of underwater target. But unfortunately stochastic noise interferes with effective recognition. We propose to use adaptive Gaussian smoothing filter to reduce stochastic noise and in section 1 we discuss theoretically how the singularity feature of the real signal can be enhanced by using adaptive Gaussian smoothing filter. The measured noise signals are the same as used in Ref.[7]. There were 560 samples; the samples for three different types of noise signals were 176, 262 and 122 respectively. After pretreatment with adaptive Gaussian smoothing filter, the recognition rates were 90.91%, 83.21% and 91.80% respectively, considerably higher than recongition rates obtained in Ref.[7]. The test results show preliminarily that our pretreatment method is quite effective.
