    • A texture description method in frequency domains and a texture-based retrieval method using the same, in which image signals are converted into those in a frequency domain of a Polar coordinate system. The texture description method in the frequency domain includes a first step of generating a frequency layout by partitioning the frequency domain into a set of feature channels; a second step of extracting the texture feature values of the image from the respective feature channels; and a third step of constituting a texture descriptor of the image in a vector form using the texture feature values extracted from the respective feature channels of the frequency layout. In a texture-based retrieval described in the frequency domain, a retrieval method capable of satisfying respective or all the retrieval conditions such as scale-, rotation- and intensity-invariant retrieval of relevant texture images is provided. Also, a retrieval method of computing the rough scheme of texture to provide a browsing functionality in retrieving is provided.
    • 频域中的纹理描述方法和使用其的基于纹理的检索方法,其中将图像信号转换为极坐标系的频域中的图像信号。 频域中的纹理描述方法包括通过将频域划分成一组特征信道来产生频率布局的第一步骤; 从各个特征通道提取图像的纹理特征值的第二步骤; 以及第三步骤,使用从频率布局的各个特征频道提取的纹理特征值,以矢量形式构成图像的纹理描述符。 在频域中描述的基于纹理的检索中,提供了能够满足相关或全部检索条件的检索方法,例如相关纹理图像的缩放,旋转和强度不变检索。 另外,提供了一种计算粗略的纹理方案以提供检索中的浏览功能的检索方法。

    • A video object segmentation method applicable to a video system is presented. The method includes primarily segmenting objects existing in a frame of a video sequence manually or semi-manually. The objects within a video sequence including the primarily segmented object are automatically segmented. The method also determines whether any scene change is made between consecutive frames or any new object other than the primarily segmented object appears within the video sequence being automatically segmented, when repeatedly performing automatically segmenting the objects within the video sequence for consecutive frames. And, the method repeatedly performs primarily segmenting objects existing in a frame of a video sequence manually or semi-manually if it is determined that any scene change is made between consecutive frames or any new object other than the primarily segmented object appears within the video sequence being automatically segmented.
    • 提出了适用于视频系统的视频对象分割方法。 该方法主要包括手动或半手动地分割存在于视频序列的帧中的对象。 视频序列中包含主要分段对象的对象将自动分段。 该方法还确定在连续帧之间是否进行任何场景改变,或者当重复执行自动分割连续帧的视频序列内的对象时,在被自动分割的视频序列中出现除主要分段对象之外的任何新对象。 并且,如果确定在连续帧之间进行任何场景改变或除了主要分段对象之外的任何新对象出现在视频序列内,该方法主要重复执行存在于视频序列的帧中的分割对象的手动或半手动 被自动分段。
