Deep Image Compression using Decoder Side Information 最后介绍一篇arxiv2020的工作《Deep Image Compression using Decoder Side Information》 论文引入side information辅助decoder端进行快速图像解码。注意这个side information和以上几篇论文中的边信息不是同一概念啊,别混淆了。且side information 仅作用在decoder端。 先...
Connectiv- ity data of the 3D model de¯nes the interpixel correlations in the projection image. Thus the wavelet transforms used in image processing do not give good results on this representation. CGAWT is de¯ned to take advantage of interpixel correlations in the image-like ...
Random-Mask Model: Test Arbitrary Masks(随机掩码模型) 上下文模型可视为权重W以二进制掩码M为条件的卷积,在以下公式中掩码M描述了上下文的模型的模式。 gcm(x)=(M⨀W)x+bgcm(x)=(M⨀W)x+b 每次反向传播,权重W会在随机掩码的引导下更新,这就隐含地建立了一个由所有以 5×5 掩码为条件的上下文模型组...
We introduce a Gaussian Mixture Model (GMM) constrained by Markov Random Field (MRF) framework for image compression in this paper. The image is predicted using GMM with MRF and the parameters of the GMM are estimated using an adjusted Expectation-Maximization (EM) algorithm. Mixture Model Optimi...
Keywords: image captioning; model compression; pruning; quantization 1. Introduction One of the most significant tasks combining two different domains such as CV and NLP is the image-captioning task [1]. Its goal is to automatically generate a caption describing an image given as an input. The...

一.Image Compression 1.主要步骤 -->神经网络编码(NN-Encoder) 基本单元:conv + downsampling + GDN 论文《Density modeling of image using a generalized normalization transformation》中首次提出GDN归一化,即generalized divisive normalization。不同于BN的局部增益控制,GDN是空间自适应的,并且可能是高度非线性的,...
Now, I will show you how to take use of the test codes for our image compression model. The file "test_imp.py" is used to test different models with different compression ratios. One model for one ratio. For each model, this file can generate the compressed image, calculate the PSNR ...

Fig. 1. Image compression model Encoder and Decoder. The choice of choosing the best compression technique depends upon the nature of system. One of those operating platforms is visual sensor network (VSN). VSN consists of a number of low cost camera sensor nodes arrayed in a region of inter...
