摘要： A preprocessing section binarizes input image data and calculates a total black pixel ratio. A feature extracting section detects connected components included in the binary image data and detects circumscribing bounding boxes of the connected components. Predetermined connected components are removed from all of the connected components based on the sizes of the detected circumscribing bounding boxes and bounding box black pixel ratios. By using the connected components that remain after removing the unnecessary connected components, a histogram is generated by specifying the sizes of the circumscribing bounding boxes as classes and numbers of the connected components as the frequencies of occurrence. A determining section determines whether the input image data is document image data or non-document image data based on information related to the generated histogram and the total black pixel ratio.

摘要： A preprocessing section binarizes input image data and calculates a total black pixel ratio. A feature extracting section detects connected components contained in the binarized image data and detects circumscribing bounding boxes that circumscribe these connected components, respectively. Based on sizes of the circumscribing bounding boxes detected and numbers of black pixels contained therein, predetermined connected components are removed. A determining section generates an edge map by using the residual connected components, and performs two-dimensional fast Fourier transform thereon to generate spectral data. The determining section performs two-dimensional fast Fourier transform on template images to generate spectral data. The determining section determines, based on these pieces of spectral data, whether or not a circular shape is contained in the input image data.

摘要： An operation method of peripheral device includes setting up connection of peripheral device to host, directly loading firmware of said peripheral device from said host, and operating said firmware by said peripheral device. The requirement of the peripheral device to non-volatile memory capacity is decreased. By pre-storing the firmware of the peripheral device in the host, the requirement of the peripheral device to non-volatile memory capacity is decreased. And it is not necessary to download the firmware in the non-volatile memory frequently when producing and debugging the peripheral device. Only loading the firmware of the peripheral device from the host directly is needed, and the efficiency is improved.
