    • An image forming apparatus includes an image forming unit that forms an image using an electrophotographic process; a color measuring unit that measures a color of the image; a measured-value acquiring unit that acquires a measured value that is measured by the color measuring unit; and a set-value deciding unit that decides a set value related to formation of the image based on a difference between the measured value and a preset target value, wherein the set-value deciding unit determines the set value so that the image approaches a reference value in a period from a current state of the image to desired state of the image while optimizing a constraint evaluation function related to a constraint condition for the formation of the image by using an estimation equation for approximating time-series variation in a state of the image.
    • 图像形成装置包括使用电子照相处理形成图像的图像形成单元; 测量图像的颜色的颜色测量单元; 测量值获取单元,其获取由所述颜色测量单元测量的测量值; 以及设定值决定单元,其基于所述测量值与预设目标值之间的差异来决定与所述图像的形成相关的设定值,其中,所述设定值决定单元确定所述设定值,使得所述图像接近参考 在从图像的当前状态到图像的期望状态的时段内的值,同时优化与用于形成图像的约束条件相关的约束条件评估函数,其中使用估计方程来近似时间序列变化的状态 图片。

    • An apparatus, method, system, computer program and product, each capable of applying document layout analysis to a document image with control of a non-character area. A non-character area is extracted from a document image to be processed. A character image is generated from the document image by removing the non-character area from the document image. The character image is segmented into a plurality of sections to generate a segmented image. The segmented image is adjusted using a selected component of the non-character image to generate an adjusted segmented image. A segmentation result is output, which is generated based on the adjusted segmented image.
    • 一种装置,方法,系统,计算机程序和产品,每个能够利用非字符区域的控制将文档布局分析应用于文档图像。 从要处理的文档图像中提取非字符区域。 通过从文档图像中移除非字符区域,从文档图像生成字符图像。 字符图像被分割成多个部分以生成分割图像。 使用非字符图像的选择分量来调整分割图像以生成经调整的分割图像。 输出分割结果,其基于经调整的分割图像生成。
