Description: JPEG压缩编码的主要步骤有：
1.通过前向离散余弦变换减少图像数据相关性；
2.利用人眼的视觉特性队DCT系数进行量化；
3.使用查分脉冲编码调制对直流系数进行编码；
4.对交流系数进行Z形扫描，使用形成长度编码队交流系数进行编码；
5.熵编码器对上述描述符进行熵编码。-JPEG compression encoding of the main steps are:
1.forward discrete cosine transform to reduce the image data
2.Using human visual characteristics of the team DCT coefficients are quantized
3.check points pulse code modulation encoding the DC coefficient
4.coefficients of the Z-scan AC coefficient is encoded using the form length encoding team
5.the entropy encoder for entropy coding of the above descriptors.

Description: H.264 is an open, licensed standard that supports the most efficient video compression techniques available
today. Without compromising image quality, an H.264 encoder can reduce the size of a digital video file by
more than 80 compared with the Motion JPEG format and as much as 50 more than with the MPEG-4
Part 2 standard. This means that much less network bandwidth and storage space are required for a video
file. Or seen another way, much higher video-H.264 is an open, licensed standard that supports the most efficient video compression techniques available

Description: 不需要os的jpeg編碼器
能夠嵌入在沒有os的fpga上或是在linux-It is an open source JPEG codec library, including both encoder and decoder.
Different to other implementations, it is designed for embedded system and is
aware of the need of embedded systems. Some advantages like
1. small memory footprint
2. easy to be ported to various processors and platforms
2. easy to run with or without embedded OS and support various embedded OS
3. easy to be ported to run with ESL tools, like Handel-C
4. easy to be ported to multi-processor systems
5. easy to can be implemented on FPGA.

Description: Watermarking is an operation of embedding infor-
mation into an image in a way that allows to identify ownership
of the image despite applying some distortions on it. In this
paper, we present a novel end-to-end solution for embedding and
recovering the watermark in the digital image using convolutional
neural networks. We propose a spreading method of the message
over the spatial domain of the image, hence reducing the local
bits per pixel capacity and significantly increasing robustness. To
obtain the model we use adversarial training, apply noiser layers
between the encoder and the decoder, and implement a precise
JPEG approximation. Moreover, we broaden the spectrum of
typically considered attacks on the watermark and we achieve
high overall robustness, most notably against JPEG compression,
Gaussian blur, subsampling or resizing. We show that an appli-
cation of some attacks could increase robustness against other
non-seen during training distortions across one group of attacks
— a proper grouping of the attacks according to their scope
allows to achieve high general robustness
