In this project, we encoding upto 100 images into a econding file which sized have been compressed, then decoding this file and generate a movie based on the reconstruct images.

First of all ,you can go to src/GUI to open GUI3.java to run our GUI. The detail insturction please follow our GUIDE:"Instruction one Vedio Encoder".

All the guide have been write into the "Instrcution on Veido Encoder", please follow this document to run our project. Also we have provide the guide vedio so that you can take a look:

• guide vedio for commandline : cmldemo
• guide vedio for GUI: GUIdemo.

What I need to mention is that the GUI3 is under src/GUI, not the root path's GUI folder.

It creates a JFrame that initiates buttons, Labels and Fields for user inputs. By using button Action Listener to call the different function in the other class.

It creats the commandline to let user can give command to encoding file and play video.

The purpose of this Class is to write the compressed data into byte stream. This class will read all images then based on their different type to do the different compression process, then output a encoding file.

The purpose of this Class is to decoding the encoding file and output a list of images.

This class mainly resize the image, once the size of image is not the times of 16*16, we need to resize it, so that our MCU unit can be work. Each time we read a image, we will call this class to initial the new size of image.

This class initial the class of Yuv, and provide the method about yuvtoRGB transfer and RGBtoYuv trasnfer.

These two classes initial the class of blocks and the class of MCU, these two classes will provide convenient to other class when dealing with the images. During the compression process, the information in data will be stored in these two kinds of class.

These two class main Grid the image into MCU types, then based on the different sampling ratio to compress the blocks in MCU.

Initial the class of MCU, sampinge blocks based on different sampling ration.

The DCT method takes a block and performs DCT. The DCT is used to remove high frequency noise within the image and assist with the inter frame compression.

Provide a quantization table determined by the quality setting input from the GUI, transfer the DCT result into a int.

Based on the result of quantizer, do the RLE for the AC part, then do the Huffman encoding to generate the final encoding result.

Based in the Huffman Encoding result to generate the images.

Based on the compressed images, generate movie by Jim2Mov lib.
