摘要:
目的:为提高血肿分割精度,提出一种基于改进Canny算子的颅内类血肿噪声检测方法。方法:首先用区域生长算 法分割出颅脑组织,去掉颅骨等干扰信息。然后使用基于改进Canny边缘检测的方法检测颅脑边缘类血肿噪声,并与原 图像进行与运算消除该噪声。最后,通过使用OTSU适应度函数的遗传算法精准分割出颅内血肿。结果:该方法在随机 抽取的200例颅脑血肿图像中,血肿检测的准确率达到96.3%,Dice相似度达到93.5%。结论:该方法能准确、有效地检测 并分割出颅内血肿。
Abstract:
Objective To propose an intracranial hematoma-like noise detection method based on improved Canny operator for improving the accuracy of hematoma segmentation. Methods The brain tissues were firstly segmented by region-growing algorithm, and the interference information such as skull was removed. Then the hematoma-like noise at the edge of brain was detected by improved Canny edge detection, and the noise was eliminated by an and operation with the original image. Finally, the genetic algorithm based on OTSU fitness function was used to segment intracranial hematoma accurately. Results In 200 randomly selected brain hematoma images, the accuracy of hematoma detection was 96.3%, and Dice similarity reached 93.5%. Conclusion The proposed method can be used to detect and segment intracranial hematoma accurately and effectively.
