使用单一的滤波器已经被证明是会导致overblurring(过度模糊) 本篇工作仿照[Zimmer et al, 2015]将合成图片分成diffuse和specular两种components,两个components独立被预处理,过滤和后处理然后合并成最后的final image Diffuse-component preprocessing 由于diffuse材质的性质(well behaved and typically has small ranges), 训...

It requires a few components(部件, 组件), which are input data, a filter, and a feature map. Let's assume that the input will be a color image, which is made up of a matrix of pixels(像素) in 3D. This means that the input will have three dimensions—a height, width, and depth...
First, let's go over out convolutional neural network architecture. There are several variations on this architecture; the choices we make are fairly arbitrary. However, the algorithms will be very similar for all variations, and their derivations will look very similar. A convolutional neural netwo...

Figure 1: A four-layer convolutional neural network with ReLUs (solid line) reaches a 25% training error rate on CIFAR-10 six times faster than an equivalent network with tanh neurons (dashed line). The learning rates for each network were chosen independently to make training as fast...
Using data management, data mining, data evaluation, data dispersion components, a novel dynamic graph convolutional network GCN is proposed which presents a never-ending learning platform called CUImage [47]. 2.1. Convolution layer A convolution operator is a generalized linear model and is ...
neural network used in deep learning. Such networks are composed of an input layer, several convolutional layers, and an output layer. The convolutional layers are the most important components, as they use a unique set of weights and filters that allow the network to extract features from the...
The convolutional layer is the core building block of a CNN, and it is where the majority of computation occurs. It requires a few components, which are input data, a filter and a feature map. Let’s assume that the input will be a color image, which is made up of a matrix of pixe...
MC simulation data of the 2-γ decay of the22Na and18F radioactive sources are employed for the training. By utilizing the GEANT4 simulation and excluding the empty matrix data where all components are 0, sufficient events are generated to train the CNN. The CNN training is performed by usi...
