    • Provided is an improved pornography blocking technique which blocks pornography on the basis of the contents of multimedia data. First, feature descriptor is extracted from multimedia data inputted from the Internet by using MPEG-7 scheme. And referring to reference pornography database which stores reference pornography in the form of feature descriptor, the similarity degree between the extracted feature descriptor and the feature descriptor of the reference pornography is measured by calculating the vector distance between the two feature descriptors. And it is determined whether the inputted multimedia data is pornography or not, by comparing the measured similarity degree with the similarity measurement threshold value. According to the invention, accurate pornography determining is possible, because the invention uses the contents of the multimedia data for determining. And rapid and efficient pornography determining is possible, because the invention uses feature descriptor with less information, instead of the original multimedia data.
    • 提供了一种改进的基于多媒体数据内容的色情内容拦截技术。 首先,通过使用MPEG-7方案从从因特网输入的多媒体数据中提取特征描述符。 并参考以特征描述符的形式存储参考色情的参考色情数据库,通过计算两个特征描述符之间的向量距离来测量提取的特征描述符和参考色情特征描述符之间的相似度。 通过将所测量的相似度与相似度测量阈值进行比较来确定输入的多媒体数据是否是色情内容。 根据本发明,由于本发明使用多媒体数据的内容进行确定,因此可以进行准确的色情判定。 因为本发明使用具有较少信息的特征描述符,而不是原始的多媒体数据,因此可以快速高效地进行色情检测。

    • The present invention relates to a method and apparatus for clearly detecting color information in front of a vehicle, and an object of the present invention is to accurately and efficiently show color-related traffic information, such as traffic lights and signs, and the whole color information of objects to color-blind people including people with dichromacy or anomalous trichromacy. The present invention provides a method of compensating for the colors of video frame data provided by a front camera, which includes the steps of compensating the video frame data, which is output from the camera, for external environment, such as surrounding colors and brightness, selecting a color range preferred by a user, compensating for the colors of the color-compensated video frame data according to the user's color blindness degree that was input or will be input, and transmitting external scenes, such as the front scene of the vehicle, to the user using a user interface considering user preference.

    • 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。
