[0049] 在本实施例中,上述步骤Sll、S13和S15中,均是由事先已经取得的图像中得到其有效区域和特征区域,只不过图像的种类不同,其有效区域的名称和特征区域的名称及特性不同。 [0049] In the present embodiment, the step Sll, S13 and S15, are obtained by the image which has previously been made in the effective region and the feature region, but different types of images, the name of the effective area and the feature region different names and characteristics. 例如,对于醋酸溶液试验图像,得到的是第一有效区域,在第一有效区域中通过比较第一色调值判断白色特征区域;对于碘溶液试验图像,得到的是第三特征区域,在第三特征区域中通过比较第三色调值得到非黑棕色特征区域。 For example, an acetic acid solution of the test image, obtained is a first effective area, the effective area of ​​the first region is determined by comparing the first characteristic white hue value; iodine solution for the test image, wherein the third region is obtained, in the third wherein the area worth black-brown feature region by comparing the third hue. 也就是说,除了使用的图像、调用的参数不同外,上述步骤中由图像得到特征区域的步骤是相同的。 That is, in addition to the use of the image, the different parameters of the call, the step of the image obtained by the above step is the same as the feature region. 请参见图2,这些步骤包括: Referring to Figure 2, the steps comprising:

[0050] 步骤S21取得图像并标记其中心点:在本步骤中,读取采集到的图像数据进入缓冲区,并设置该图像采集时的十字标记交叉点为其中心点,记录该中心点的坐标;其中,在本步骤中取得的图像可以是醋酸溶液试验图像、醋酸溶液试验的绿光图像、生理盐水试验图像、生理盐水试验绿光图像或碘溶液试验图像中的一个。 [0050] Step S21 acquired image and mark its center point: In this step, read acquired image data into the buffer, and set the cross mark image acquisition when the center point of its intersection point, the center point of the recording coordinate; wherein the image acquired in this step, the test image may be acetic acid, acetic acid green solution test image, the test image saline, physiological saline or test green image iodine solution in a test image.

[0051] 步骤S22得到图像的有效区域:在本步骤中,根据上面步骤中取得图像的轮廓识别得到该图像的有效区域;其中,由所述醋酸溶液试验图像、醋酸溶液试验的绿光图像和碘溶液试验图像分别得到第一有效区域、第二有效区域和第三有效区域;每个图像的中心点与由其得到的有效区域的中心点重合; [0051] Step S22 to obtain an effective area of ​​the image: In this step, the effective region of the image acquired in the above step according to the contour of the identification image; wherein the green image of the test image, the test solution of acetic acid and acetic acid iodine solution of the test image to obtain a first effective area, a second effective area and the third effective area; coincides with the center point of each image by the effective area of ​​the center point obtained;

[0052] 步骤S23判断有效区域内的特征区域:在本步骤中,将得到的有效区域内的图像数据由RGB计算颜色模型转换为HIS,并判断是否有色调值超过该有效区域对应的预定色调值,从而得到对应的特征区域;同样地,对于醋酸溶液试验图像而言,其第一有效区域对应第一预定色调值,执行本步骤后得到白色特征区域;对于醋酸溶液试验的绿光图像而言,第二有效区域对应第二预定色调值,执行本步骤后得到黑色特征区域;对于碘溶液试验图像而言,其第三有效区域对应第三预定色调值,执行本步骤后得到非黑棕色特征区域等等。 [0052] Step S23 determines feature region within the effective region: In this step, the image data within the effective area obtained is calculated from the RGB color model into the HIS, and judges whether the hue value exceeds a predetermined color tone of the valid region corresponding to value, thereby obtaining a corresponding feature region; Likewise, for the test image in terms of acetic acid solution, a first effective area corresponding to a first predetermined tone value, wherein the white area obtained after this step is performed; green image for the acetic acid test solution words, a second effective area corresponding to a second predetermined tone value, the feature region to obtain a black present after performing step; iodine solution for test images, which corresponds to a third predetermined third effective area of ​​the tone values ​​after the execution of this step to give black-brown feature area, and so on.

[0053] 下面以醋酸溶液试验图像为例,说明在本实施例中,如何对一个图像按照图2中所示的方法具体进行有效区域和特征区域的识别。 [0053] In the following an example an acetic acid solution of the test image, described in the present embodiment, how to identify a specific effective image region and the feature region by the method shown in FIG. 其他的图像,例如醋酸溶液试验绿光图像、碘溶液试验图像、生理盐水试验图像和生理盐水试验绿光图像的有效区域和特征区域的识别与取得都与下面的描述相似,不同的是图像数据、以及判断参数不同。 Other images, such as identification and acetic acid to obtain a valid test area green image, the test image iodine solution, saline and saline trials test image and the green image are similar to the feature region described below, except that the image data and determination of different parameters.

[0054] 在醋酸溶液试验图像中,图像轮廓识别方法可以采用数学形态法(用形态学算子(腐蚀、膨胀、开、闭)及其组合进行形状和结构的分析及处理)、基于梯度的方法(检查边界像素的邻域灰度的变化率和方向,以此确定轮廓边界)、活动轮廓模型法(把图像中感兴趣的物体轮廓看作一条连续、封闭的链条结构,为它设计一类能量函数,以迭代方式求取能量的最小值,从而获得最优轮廓)等。 [0054] In acetic acid solution the test image, the image outline recognition method may be used on Mathematical Morphology (analyze and process the shape and structure of morphological operators (erosion, dilation, opening, closing), and combinations thereof), gradient-based the method (rate of change and direction of neighborhood gray check boundary pixels, thereby determining a boundary contour), active contour model method (the object of interest in the contour image is regarded as a continuous, closed-chain structure, which is designed as a based energy function, iteratively obtaining the minimum value of the energy, so as to obtain the optimum contour) and the like. 然后识别采集的宫颈的醋酸溶液试验图像的第一有效区域中色调值超过预设定色调值的白色特征区域的分布。 Then identifying a first collection of cervical effective region acetic acid test image tone value exceeds the pre-set tone value distribution characteristic white areas.

[0055] 在本实施例中,色调值是指HIS (色调(Hue)-亮度(Intensity)-饱和度(Saturat1n))视觉颜色模型中的色调分量值。 [0055] In the present embodiment, the tone value is HIS hue component values ​​(hue (Hue) - Saturation (Saturat1n) - luminance (Intensity)) visual color model. 将图像从RGB计算颜色模型转换至HIS,并对色调分量进行分析可以降低图像的维度,减少运算量。 The calculation of the color conversion from RGB to HIS model image, and the hue component analysis can reduce the dimensions of the image, reducing the amount of calculation.

[0056] 在本实施例中,得到任何一个特征区域后,还可以将得到的特征区域做如下处理(仍然以白色特征区域为例): After [0056] In the present embodiment, a feature region to obtain any further obtained feature region may be processed as follows (wherein the white region still as an example):

[0057] 将该图像采集时的十字坐标的交点(即取得的醋酸溶液试验图像的中心点)与预设置的用于后续宫颈活检显示坐标图的中心坐标对齐;在所述用于后续宫颈活检显示坐标图上与阴道镜采集的宫颈的醋酸溶液试验图像白色特征区域对应位置处进行标记。 [0057] The intersection of the cross mark image acquisition time (the center point of the test image, i.e. acetic acid solution obtained) and for subsequent preset the display center coordinates cervical biopsy FIG aligned; for the subsequent cervical biopsy graph displayed on the cervix and colposcopy acquired acetic acid white test image at a position corresponding to the feature region marked.

[0058] 具体标记的方式,请参见图3,以所述特征区域中心点为圆心,使用多个同心圆划分所述图像,使用多条均匀分布在圆周上的直径将已经划分的图像再次划分,得到多个区域。 [0058] DETAILED marked manner, see Figure 3, wherein the center point of a circle area, dividing the image using a plurality of concentric circles with a diameter uniformly distributed over the circumference of the plurality of divided images that have been divided again to obtain a plurality of regions. 即将宫颈的醋酸溶液试验图像的第一有效区域以该图像采集时的十字坐标中心坐标为中心,从内向外,分成近、中、远3等份;与表盘结构相似,以十字坐标中心坐标为中心,以顺时针为方向分成12等份,共36个区域。 A first effective area is about cervical acetic acid to cross the test image coordinates of the center coordinates of the center of the image acquisition, from the inside out, divided into near, intermediate and distance 3 aliquots; and dial structure similar to a cross coordinate center coordinates center, in a clockwise direction is divided into 12 equal parts, a total of 36 regions. 对应时,将36个区域分别与后续宫颈活检显示坐标图上的36个交点一一对齐。 When the corresponding, respectively, to 36 and subsequent cervical biopsy region 36 displayed on the intersection graph correctly aligned. 值得一提的是,在本实施例中,所有的对其及标注都是采用这种方式的。 It is worth mentioning that, in the present embodiment, and all its labels are in this way.

[0059] 上述标记的好处是,可以将自动分析出的阴道镜采集的宫颈的醋酸溶液试验(醋酸溶液试验绿光)图像的特征实时显示出来,并且对应到用于后续宫颈活检显示坐标图上,供医生参阅;同时若在此步骤中已足够能够分析出最终结果时可以及时中断后续分析,减少分析的时间及工作量,提高效率。 [0059] The advantage is that the marker may be an automatic analyzer collected cervical colposcopic tests of acetic acid (acetic acid test green) image is displayed in real time, and corresponds to the display coordinates for subsequent cervical biopsy FIG. for doctors to see; timely interruption subsequent analysis in the same time if this step is enough able to analyze the final result, reduce the time and effort of analysis and improve efficiency.

[0060]当然,在对其他图像做出特征分析时,也是每得到一个特征区域就进行这样的标注,其好处也是相似的。 [0060] Of course, in making the analysis of the other image feature, a feature region is obtained for each such annotation proceeds, its benefits are similar.

[0061] 此外,在本实施例中,还可以在执行所述步骤Sll之前,提取采集到的生理盐水试验图像,并对其进行特征区域分析;生理盐水试验图像的特征区域为原始特征区域,原始特征区域对应原始色调值,比较后得到红色特征区域;得到的红色特征区域同样可以单独与宫颈活检显示坐标图叠加或/和参与最后的多个特征区域的叠加。 [0061] In addition, the test image saline embodiment, may also be performed prior to the step Sll, extract collected in the present embodiment, and subjected to analysis feature region; saline test feature region image into the feature region of the original, original tone values ​​wherein corresponding original region after comparing the feature region to obtain a red; obtained feature region may also be red and cervical biopsy alone graph overlay superimposed and / or involved in the final plurality of characteristic regions. 这样使得得到的特征区域较多,更为完善,便于得到准确的评估结果。 Such that the obtained feature region larger, more complete, accurate and easy to obtain evaluation results. 对于图像的分析、红色特征区域的取得方式等,均与上述方式的相似。 For the analysis of the images, the feature region to obtain a red way, it is similar to the above embodiment.

[0062] 此外,在本实施例中,为了进一步验证黑色特征区域,以得到更为准确的结果,在上述取得黑色特征区域的步骤中还可以包括一个验证步骤,即取得生理盐水试验图像的绿光图像,判断其黑色特征区域,并与已经得到醋酸溶液试验绿光图像的黑色特征区域比较,取其重叠部分作为最后的黑色特征区域。 [0062] Further, in the present embodiment, in order to further verify the black feature region to obtain more accurate results, wherein the step of obtaining the black area above may further include a verification step of obtaining the test image of green saline light image, wherein the black area which is determined, and compared with the acetic acid solution has been green test feature region image is black, whichever overlapping portion as the last black feature region.
