Description: 视频拼接Filter。将2路视频拼成一路输出。非压缩的RGB和YUV格式，输入端格式必须一致，第一路视频决定输出的帧率。写这个Filter主要是为了把两路视频采集到一个文件中，如果只是要把多路视频合成后显示的话，建议使用VMR-9-Video Mosaic Filter. Will be two video output as guarding our way. Non-compressed RGB and YUV format, input must be consistent format, the first video output frame rate decision. Filter wrote this mainly to the two video collection to a document, If only multi-channel video should Synthesis shows the proposed use of VMR-9 Platform: |

Description: ECE345, Visual-to-Audio Electronic Travel Aid
Code for TM320C54x (v2a.asm) download
This project involves the design and implementation of a audio synthesis device that converts moving images into audio signals. The system is built on a TM320C54x DSP with interface to an IMAQ camera module via the serial port on a PC. Brief description: A LabVIEW VI acquires an image from the IMAQ camera module. It quantizes the image into a 5x5, 3-bit image, and sends the data to the TM320C54x DSP via a serial port. The TM320C54x DSP constructs a 64-tap FIR by combining a series of 64-tap head related transfer functions (HRTF) according to the incoming data, and then filters an input audio signal with this FIR filter, in effect creating a correspondence between the filtered signal and the original image. -ECE345, Visual-to-Audio Electronic Travel Aid Code for TM320C54x (v2a.asm) download This project involves the design and implementation of a audio synthesis device that converts moving images into audio signals.
