Main Projects

>Designed and Implemented algorithm for Automatic Pavement Distress Detection and Classification System.

#Enhanced the image quality. Removed the non-uniform background illumination.

#Thresholded the pavement image to get binary crack image, then used Beamlet Transformation to extract the crack information.

#Performed crack extension check and classified cracks.

>Research the hardware architecture of Multi-Core DSP CT3400, to implement image compression algorithm JPEG on CT3400 in different ways, and to compare the performance of different implementation ways.

#Installed Cradle RDS-3400 development/evaluation board onto computer.

#Implemented JPEG algorithm in ANSI C under Visual Studio.

#Measured image compression performance – MSE (Mean Square Error), PSNR(Peak Signal Noise Ratio) and processors' processing time; compare these two kinds of data in different implementation ways.

>Developed the solution for HDTV with support of progressive scan, 1080i/1080p/720p and VGA input. The product has been masked and mass produced in HISENSE and SKYWORTH.

#Communicating with customers and hardware engineers, make the Customer Requirement Specification and Software Requirement Specification.

#Designed the User Interfaces, including user mode, design mode, and factory mode.

#Made the unit test, integration test and validation test plans.

#Developed the drivers for all the peripheral hardware.

#Coding, Debugging, Verification, Validation and Documentation.

#Provided ongoing support according to customers’ requirement.

>Developed a LCD TV solution. The product has been masked and mass produced in HAIER and PANDA.

>Developed the High Definition LCD TV reference software TV506E. The product has been masked and mass produced in SKYWORTH.

>Designed and implemented a game (Box-man) which is display on TV and played with remote controller.

>Built the On-Screen-Display (OSD) driver and function library for TMP88CS34N.
