摘要:

在本文中,我们提出了一种新的图像描述符,称为形成局部交叉投影(FLIP)和它的多分辨率版本(mFLIP)表示组织病理学图像。该描述符是基于Radon变换,其中我们应用并行投影在小的局部邻域的灰度图像。在每个窗口中使用等距投影方向,我们通过取相邻投影的交集来提取邻域的唯一不变特征。然后,我们为每个图像构建一个直方图,我们称之为FLIP直方图。不同的分辨率提供不同的FLIP直方图,然后将其连接以形成mFLIP描述符。我们的实验包括从头开始训练常见的网络,以及微调预训练的网络来对我们提出的描述符进行基准测试。实验在公开可用的数据集KIMIA Path 24和KIMIA Path 960上进行。对于这两个数据集,FLIP和mFLIP描述符在所有实验中都显示出了令人满意的结果。使用KIMIA Path 24数据,FLIP在特征提取方面优于未微调的Inception-v3和微调的VGG 16,而mFLIP在特征提取方面优于微调的Inception-v3。

英文摘要:

In this paper, we propose a novel image descriptor called Forming Local Intersections of Projections (FLIP) and its multi-resolution version (mFLIP) for representing histopathology images. The descriptor is based on the Radon transform wherein we apply parallel projections in small local neighborhoods of gray-level images. Using equidistant projection directions in each window, we extract unique and invariant characteristics of the neighborhood by taking the intersection of adjacent projections. Thereafter, we construct a histogram for each image, which we call the FLIP histogram. Various resolutions provide different FLIP histograms which are then concatenated to form the mFLIP descriptor. Our experiments included training common networks from scratch and fine-tuning pre-trained networks to benchmark our proposed descriptor. Experiments are conducted on the publicly available dataset KIMIA Path24 and KIMIA Path960. For both of these datasets, FLIP and mFLIP descriptors show promising results in all experiments.Using KIMIA Path24 data, FLIP outperformed non-fine-tuned Inception-v3 and fine-tuned VGG16 and mFLIP outperformed fine-tuned Inception-v3 in feature extracting.
