    • There are provided an image analyzing apparatus and an image analyzing method where, in analyzing a microscopic image of a microbe or a cell tissue, the manpower-independent observation and quantification are executed so as to enhance the analyzing performance. The configuration of the apparatus and the method is as follows: A frequency conversion processing, such as Wavelet transformation, is executed toward the microscopic image of the microbe or the cell tissue and, based on the result obtained, the quantitative analysis is executed. The configuration allows the automatic quantitative judgement to be executed concerning factors such as the position, the number, the magnitude, the degree of activity, the area ratio, the configuration, the direction, and the color. This condition makes it possible to reduce a burden imposed on a person who are in charge of the observation. Also, the noise can be eliminated, which also enhances the analyzing performance. Moreover, the converted regions are utilized for the analysis. This condition makes it possible to execute the analysis with the amount of calculation that is smaller than the resolution, thereby allowing the high-speed processing to be implemented.
    • 提供了一种图像分析装置和图像分析方法,其中,在分析微生物或细胞组织的微观图像时,执行人力无关的观察和定量,以提高分析性能。 该装置和方法的结构如下:对微生物或细胞组织的微观图像执行诸如小波变换之类的变频处理,根据获得的结果,进行定量分析。 该配置允许对诸如位置,数量,大小,活动程度,面积比,配置,方向和颜色等因素执行自动定量判断。 这种情况可以减轻负责观察者的负担。 此外,可以消除噪声,这也增强了分析性能。 此外,转换的区域用于分析。 该条件使得可以以小于分辨率的计算量执行分析,从而允许实现高速处理。

    • In an image data processing system, an insignificant space estimation unit predicts a significant/insignificant space in a high-frequency subband on the basis of a low-frequency subband signal in a wavelet space. A deletion unit deletes data in the insignificant space which is predicted by the insignificant space estimating unit. Here, the data is contained in the high-frequency subband. An error-estimation detection unit detects presence of significant data in the space predicted to be insignificant by the insignificant space estimation unit. An adding unit adds to output data a significance attribute indicating that significant data exists in the space detected by the error-estimation detection unit.
    • 在图像数据处理系统中,无效空间估计单元基于小波空间中的低频子带信号预测高频子带中的有效/无效空间。 删除单元删除由无效空间估计单元预测的无效空间中的数据。 这里,数据被包含在高频子带中。 误差估计检测单元通过无效空间估计单元检测预测为无效的空间中的有效数据的存在。 添加单元向输出数据添加指示在错误估计检测单元检测到的空间中存在有效数据的显着性属性。
