A on-board ship targets detection method based on multi-scale salience enhancement is proposed. Unlike the traditional wavelet filter enhancement methods, the proposed utilizes the wavelet decomposition to obtain the high-low frequency parts, and estimate the salience feature with both parts, which enhance the ship targets efficiently. First, decompose the remote sensing image by 2-D DWT, and obtain...
Detection of ship targets in the sea area is an important field in remote sensing image target detection. As the ships and the surrounding areas are very different in texture, that makes it a possible solution to detect the ships using the texture feature. Aiming at the detection of ship targets, a novel ship target detection algorithm in a large scene of the optical remote sensing image is proposed...
Optical remote sensing satellite holds great potential for ship detection. However, it is challenging for real-time detection due to the relatively low resolution and complicated background. We propose a real-time on-board ship detection method based on statistical analysis and shape identification. First, Gaussian and median filter are used to reduce the periodical and pepper noise generated by the...
Multi-focus image fusion is a process of obtaining a new all in-focus merged image from two or more partially defocused images of the same scene and same imaging condition. The merged image includes the information of the original images and improves the reliability and intelligibility for object detection and target recognition. The most widespread methods for image fusion are wavelet transform based...
