Avi2Movie 1.00 18.12.2000 (c) by R.Rawer '99-'01 =============================================================================== (1) Contents =============================================================================== (1) Contents (2) About Avi2Movie (3) Syntax of Avi2Movie (4) Possible Code Modifications (5) History of Changes (6) Contact the Autor =============================================================================== (2) About Avi2Movie =============================================================================== Avi2Movie is a simple m-file to read the images of uncompressed AVIs into MatLab and store them as a MatLab Movie-Dataset. Avi2Movie is based on AviRead. (*1*) the section where the bytestream read from the AVI-file is transformed into a matrix (*2*) the section where you can add you own code to do caculations based on the picture data Both sections are marked in the source code. =============================================================================== (3) Syntax of Avi2Movie =============================================================================== Syntax: Result = Avi2Movie(filename, number of frames to process, first frame to display, last frame to display) Result : selected frames stored as one MatLab Movie-Dataset Example: Avi2Movie('sample.avi',30,10,12) reads and processes the first 30 frames of the file 'sample.avi', and saves frame 10, 11 and 12 as one MatLab Movie-Dataset. =============================================================================== (4) Possible Code Modifications =============================================================================== AviRead justs reads the image data of AVI-files. In order to process this image data you probably need to modify the the code in section (*2*). If anothe arrangement of the pixelinformation is needed also modify section (*1*) ind AviRead.m. Use the folowing variables within your image processing routines: no_of_frames: number of frames to be read time_per_frame: time to display each frame [ms] (reverse of frames per 0.001 second) frames: number of this frame columns: number of pixels per line lines: number of lines per image bytes: number of bytes per pixel im: image data: 8bit/pixel: uint8-Matrix[columns,lines] 16bit/pixel: uint16-Matrix[columns,lines] 24bit/pixel: uint8-Matrix[columns,lines,3] (3 Color Planes R,G,B) 32bit/pixel: uint32-Matrix[columns,lines] xx: raw image data: 8bit/pixel: uint8-Matrix[columns*lines] (1-dimentional) 16bit/pixel: uint16-Matrix[columns*lines] (1-dimentional) 24bit/pixel: uint8-Matrix[3,columns*lines] (1-dimentional, 3 Color Planes R,G,B) 32bit/pixel: uint32-Matrix[columns*lines] (1-dimentional) =============================================================================== (5) History of Changes =============================================================================== V1.00 (22/12/2000): ------------------- Generated Avi2Movie from AviRead V1.13 =============================================================================== (6) Contact the Author =============================================================================== rrawer@gmx.de http://www.rawer.de/rainer/software/ ===============================================================================
