    • The present invention generally relates to a method and apparatus for creating an harmony map of an image. It also relates to a method and apparatus for assessing the quality of an image. The invention also relates to a method and apparatus for assessing the quality of an image such that an assessment score of the image is obtained from a perceptual map of the image created from the previous method. As an interesting tool for content creator and in the goal of maximizing the artistic effect, the proposed method provides perceptual harmony-guided quality map as well as a score of disharmony of a picture without reference image. The method links two distinct subjects: perceptual quality metric and harmonious hue templates in order to provide new tools to content creator whatever the expertise level.

    • Provided is an image processing apparatus according to which, even when a relationship between the magnitudes of brightness values of objects that belong to the same category is inverted, feature amounts that are similar to the extent that the objects can be recognized as belonging to the same category are acquired. The image processing apparatus includes an image acquiring unit (11) configured to acquire an image, and a feature amount acquiring unit (12, 13) configured to acquire feature amounts that correspond to the acquired image by performing a predetermined arithmetic operation on the image, and to output the acquired feature amount, wherein when the acquired feature amounts include a negative value, the feature amount acquiring unit replaces the negative value with the absolute value of the negative value.

    • A system, method, and computer program product that may use a cache in the decompression of block compressed image data. Each data entry in the cache may represent decompressed image data corresponding to a compressed block of an image. The indices of the cache are keys, where each key is the output of a hash process that is performed on the corresponding compressed block. Decompression of a compressed block may be performed by hashing the compressed block to generate the key. The key may be used to access the cache. The decompressed data indexed by the key may be read and used as the decompressed version of the compressed block. If no data corresponds to the key, or if the cached data indexed by this key is otherwise invalid, then a conventional decompression process may be applied to the compressed block to yield the decompressed data. This decompressed data may then be written to the cache, at a location corresponding to the key.
    • 可以在块压缩图像数据的解压缩中使用高速缓存的系统,方法和计算机程序产品。 高速缓存中的每个数据条目可以表示对应于图像的压缩块的解压缩图像数据。 缓存的索引是密钥,其中每个密钥是在对应的压缩块上执行的散列过程的输出。 压缩块的解压缩可以通过对压缩块进行散列来产生密钥来执行。 密钥可用于访问缓存。 由密钥索引的解压缩数据可以被读取并用作压缩块的解压缩版本。 如果没有数据对应于密钥,或者如果由该密钥索引的缓存的数据否则无效,则可以将常规的解压缩过程应用于压缩块以产生解压缩的数据。 然后可以在对应于该键的位置将该解压缩的数据写入高速缓存。

    • A color arrangement checking device stores a full-color document in which elements of each color are placed on a page, detects at least a color and a size of the elements for each page of the document, adds up the size of the elements for the whole page by the color which is output as an occupancy ratio, and determines whether or not at least one of brightness and saturation exceeds a predetermined color threshold value for each color of the elements. The color arrangement checking device determines whether or not the occupancy ratio by the color of the elements, which assume the color, of which at least one of the brightness and the saturation is determined to exceed the color threshold value, as an attribute, exceeds a predetermined occupancy threshold value, and outputs the elements which assume the color, of which the occupancy ratio is determined to exceed the occupancy threshold value, as the attribute.
