ops.py中是python中调用C++代码的入口,真正的计算都在这里执行,其中有两个重要的函数:get_indice_pairs和indice_conv,get_indice_pairs负责根据输入索引和空间shape以及卷积核等信息计算输出索引(outids)和输入输出索引对应关系(indice_pairs),indice_conv负责根据特征,卷积核和indicePairs以及indiceNum计算卷积,后面详细...
Given a classified probabilistic shape dictionary, and an image with a shape similar to some of the elements in the dictionary, this letter introduces a sparse representation based framework with a twofold goal. First, to select a sparse shape combination from the dictionary that best represents th...
树木稀疏。 We perceive the shape of the heart only because our brains impose a shape on to a very sparse field of data. 我们意识到那是心形只是我们的大脑将一些零散的形状勉强凑成一个整体。 For such sparse sampling to work, advanced, broadcasting civilizations would have to be abundant, or...

We propose a segmentation framework based on both prior shape knowledge and image intensity. Instead of the strong request of the pre-segmentation of cine MRI in the same session, we use the sparse representation method to model the myocardium shape. Data from the Cardiac MR Left Ventricle ...

Our method works by combining random forest (RF) regression based landmark de- tection with sparse shape composition model based landmark correction. Validation on 100 cephalometric X-ray images show that 77.79% land- marks can be detected by our method with an error less than 4.0 mm. 展开 ...
