Blood leucocytes segmentation in medical images is viewed as difficult process due to the variability of blood cells concerning their shape and size and the difficulty towards determining location of Blood Leucocytes. Physical analysis of blood tests to recognize leukocytes is tedious, time-consuming and liable to error because of the various morphological components of the cells. Segmentation of medical imagery has been considered as a difficult task because of complexity of images, and also due to the non-availability of leucocytes models which entirely captures the probable shapes in each structures and also incorporate cell overlapping, the expansive variety of the blood cells concerning their shape and size, various elements influencing the outer appearance of the blood leucocytes, and low Static Microscope Image disparity from extra issues outcoming about because of noise. We suggest a strategy towards segmentation of blood leucocytes using static microscope images which is a resultant of three prevailing systems of computer vision fiction: enhancing the image, Support vector machine for segmenting the image, and filtering out non ROI (region of interest) on the basis of Local binary patterns and texture features. Every one of these strategies are modified for blood leucocytes division issue, in this manner the subsequent techniques are very vigorous when compared with its individual segments. Eventually, we assess framework based by compare the outcome and manual division. The findings outcome from this study have shown a new approach that automatically segments the blood leucocytes and identify it from a static microscope images. Initially, the method uses a trainable segmentation procedure and trained support vector machine classifier to accurately identify the position of the ROI. After that, filtering out non ROI have proposed based on histogram analysis to avoid the non ROI and chose the right object. Finally, identify the blood leucocytes type using the texture feature. The performance of the foreseen approach has been tried in appearing differently in relation to the system against manual examination by a gynaecologist utilizing diverse scales. A total of 100 microscope images were used for the comparison, and the results showed that the proposed solution is a viable alternative to the manual segmentation method for accurately determining the ROI. We have evaluated the blood leucocytes identification using the ROI texture (LBP Feature). The identification accuracy in the technique used is about 95.3%., with 100 sensitivity and 91.66% specificity.
医学图像中的血白细胞分割被视为困难的过程,因为血白细胞的形状和大小存在可变性,并且难以确定血白细胞的位置。通过物理分析血液测试来识别白细胞是繁琐、耗时且容易出错的,因为细胞的各种形态成分。由于图像的复杂性,以及由于缺乏完全捕获每个结构中可能形状的白细胞模型,并且还包含细胞重叠,血白细胞的形状和大小的广泛变化,影响血白细胞外观的各种因素,以及由于噪声而导致的静态显微镜图像差异较小,因此医学图像的分割被认为是一项困难的任务。我们提出了一种使用静态显微镜图像进行血白细胞分割的策略,该策略是计算机视觉三个主要系统的结果:增强图像,支持向量机用于分割图像,以及基于局部二值模式和纹理特征过滤掉非 ROI(感兴趣区域)。这些策略中的每一个都针对血白细胞分割问题进行了修改,因此与单独的部分相比,后续技术非常强大。最终,我们基于比较结果和手动分割来评估框架。这项研究的结果表明了一种新的方法,可以自动分割血白细胞并从静态显微镜图像中识别出来。最初,该方法使用可训练的分割过程和训练的支持向量机分类器来准确识别 ROI 的位置。之后,基于直方图分析提出了过滤掉非 ROI 的方法,以避免非 ROI 并选择正确的对象。最后,使用纹理特征识别血白细胞类型。该预测方法的性能已在不同规模的妇科医生通过系统进行手动检查的情况下进行了测试。总共使用了 100 张显微镜图像进行比较,结果表明,该解决方案是手动分割方法的一种可行替代方法,可用于准确确定 ROI。我们使用 ROI 纹理(LBP 特征)评估了血白细胞的识别。该技术的识别准确率约为 95.3%,具有 100%的灵敏度和 91.66%的特异性。
