Image retargetting aims at automatically adjusting the size of a given image to fit the arbitrary displays without introducing severe visual distortions. Salient detection plays a key role in image retargeting to preserve visually important image content. We propose a new salient region detection method and an improved seam carving scheme for image retargeting. Our main contribution includes: we design...
Vehicle identification is one of the key technologies to achieve road transport automation and the deep research of this technology has important practical significance to the development of intelligent transportation. Because image backgrounds of car models are complex, and the count of car models is too large, model identification has long been a research hotspot and difficult. This paper mainly...
There are the problems such as slow identification, poor anti-interference capability in the traditional edge detection. In this paper, it analyzes the different traditional detection algorithms and experimental results. Based on the analysis, it proposes out the edge detection algorithm based on wavelet, and analyzes the effect of wavelet edge detection.
The advantage of wavelet technology can separate the signal and the noise, thereby enhancing the output the ratio of signal to noise. In the outdoor environment, under the high noise, it proposes one algorithm based on dyadic wavelet to process the signals and noises in images of vehicles through the wavelet transform at different scales and different characteristics, which can adjust its threshold...
