    The adverts of various image-acquiring devices have tremendously increased the amount of image. Thus, there is an expansion in the necessity of image-based applications in various areas. The irregularity of images, however, becomes a big obstacle in constructing these applications. The extraction of robust salient points from image plays an important role in solving this problem. For achieving it, many salient point extraction algorithms, such as Harris corner, SIFT and SURF etc., have been introduced. Most of them, however, are focused on extracting corner points or edges of object. In this research, we introduce a technique of extracting directional salient points based on wavelet transformation. The proposed method can extract robust salient points related to the character of the image. This makes it possible to construct various applications which are related to the image.

    Multiple Audio Object Coding for Interactive Audio Service

    Kwangki Kim , Jang, Byeong-Ok | 2013, 8(6) | pp.63~70 | number of Cited : 1
    Abstract PDF
    Interactive audio service allows users to create and enjoy their audio sound according to their preferences using delivered audio objects such as vocal, bass, piano, guitar, drum, and so on. The interactive audio service has very high bit-rate because various audio objects are separately coded. Therefore, it is difficult to provide the interactive audio service through the wired/wireless communication and network environment. To solve the bit-rate problem of the interactive audio service, multiple audio object coding (MAOC) scheme can be applied. The basic idea of the MAOC is that the audio objects are represented as a down-mix signal with spatial parameters. However, because the MAOC still has a problem that the precise control of a particular audio object is impossible, the sound quality degradation is very severe in a Karaoke service. In this paper, we proposed the enhanced MAOC that focus on the precise control of the target object such as vocal. The enhanced MAOC uses a residual signal that indicates the gap between the parametric description of the audio signals and the transparent sound quality. From the experimental result, the proposed enhanced MAOC shows better performance than the MAOC in the aspect of the precise control of the target audio object.
