Design and Develop a test tool using Django, HTML, JavaScript, JQuery, CSS, python and sqlite3. The core at backend is using python. It creates one thread for each test case and generates JSON files which holds data to communicate with the front end. The front end is developed using Django, HTML, JavaScripts, JQuery and CSS. The database chosen is sqlite3. As Django handles the interface with database, SQL is not used in the project. The test result is collected from the testing device using… Show more

Try to find out a good and quick method to analyze photo quality. Judge photo quality according to exposure, noise and blurriness. Exposure is measured based on analyzing grey histogram and calculating ratio between left and right part of grey histogram. Then this ratio will be compared with distribution of peak value to determine whether exposure is enough or not. For image blur estimation, slope of the natural image amplitude spectrum and image edge distortion are used to judge image quality.… Show more

For image blur estimation, slope of the natural image amplitude spectrum and image edge distortion are used to judge image quality. For noise estimation, estimation is based on Laplacian operator and FDBP analysis. Finally, these three factors are combined together and used in ID photo quality assessment. Show less

Implemented coherent controller between two 5 stage pipeline microprocessors with cache using VHDL. First implemented single-cycle processor, then a pipe-line processor. Then implemented a pipe-line processor with cache. Finally, finished a dual-core microprocessors with cache. All hardware testing are done by using quartus on FPGA.

The features of our design included serial communication using UART protocol, DES encryption, Dynamic CRC noise detection and NDEF server implementation. Using VHDL code to implement all these protocol and analyze the budget of the design.

I wrote the a tic-tac-toe game program with combination of C and assembly language and helped to implement it with a micro coded 3-bus computer, LED matrices and other electronic devices in Microprocessor System Design and Interface.

Worked as a leader of a four people group and was responsible for the main part of the project. The aim of my project is to count the traffic flow in one intersection of a road. It was using blob track algorithm to track cars. opencv libraries and MFC were also used in this project.
