An Automatic Method for Image Matting Based on Saliency Detection ⋆

چکیده
Image matting aims at extracting foreground from a given image by means of color and alpha estimation. An automatic matting method based on saliency detection was proposed in this paper, which takes the advantages of saliency detection as prior information instead of user interaction. After getting the saliency map, a cost function was constructed to obtain an alpha matte. Moreover, with the intention of further optimizing this alpha matte, iterative boundary search was introduced to search matting failed pixels. The experimental results show that the new method outperforms state-of-the-art image matting methods in terms of speed and alpha matte accuracy.

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 کاملA Saliency Detection Model via Fusing Extracted Low-level and High-level Features from an Image
Saliency regions attract more human’s attention than other regions in an image. Low- level and high-level features are utilized in saliency region detection. Low-level features contain primitive information such as color or texture while high-level features usually consider visual systems. Recently, some salient region detection methods have been proposed based on only low-level features or hig...

In this paper, a novel saliency theory based RR-IQA metric is introduced. As the human visual system is sensitive to the salient region, evaluating the image quality based on the salient region could increase the accuracy of the algorithm. In order to extract the salient regions, we use blob decomposition (BD) tool as a texture component descriptor. A new method for blob decomposition is propos...

The problem of accurate foreground estimation in images is called Image Matting. In image matting methods, a map is used as learning data, which is produced by those pixels that are definitely foreground, definitely background ,and unknown. This three-level pixel map is often referred to as a trimap, which is produced manually in alpha matte datasets. The true class of unknown pixels will be es...
