Saliency Detection For Maritime Search And Rescue Using SVD To The Amplitude Spectrum
نویسندگان
چکیده
A novel saliency detection method for maritime search and rescue using singular value decomposition to the amplitude spectrum is proposed. Color and intensity features of images are extracted and amplitude spectrums of them are obtained by Fourier transform. Singular value decomposition (SVD) is conducted on the amplitude spectrums and the saliency maps are defined as the inverse Fourier transform of the difference between amplitude spectrums and their main components based on certain threshold. The color and intensity saliency maps are combined to achieve the master map. Experiments are made to show the validity and effectiveness.

Compressed-Sampling-Based Image Saliency Detection in the Wavelet Domain
When watching natural scenes, an overwhelming amount of information is delivered to the Human Visual System (HVS). The optic nerve is estimated to receive around 108 bits of information a second. This large amount of information can’t be processed right away through our neural system. Visual attention mechanism enables HVS to spend neural resources efficiently, only on the selected parts of the...
متن کاملGraph-based Visual Saliency Model using Background Color
Visual saliency is a cognitive psychology concept that makes some stimuli of a scene stand out relative to their neighbors and attract our attention. Computing visual saliency is a topic of recent interest. Here, we propose a graph-based method for saliency detection, which contains three stages: pre-processing, initial saliency detection and final saliency detection. The initial saliency map i...

Nowadays, due to quality development of satellite images, automatic target detection on these images has been attracted many researchers' attention. Remote-sensing images follow various geospatial targets; these targets are generally man-made and have a distinctive structure from their surrounding areas. Different methods have been developed for automatic target detection. In most of these met...

As a component of low-level vision processing, saliency detection facilitates subsequent processing such as object detection or recognition. In this paper, we argue that a reasonable saliency detector should have the ability to: (1) Detect both small and large saliency regions. The size of salient regions vary greatly. When the salient region is large, however, because center-surround algorithm...
