There will be startup folder containing a startup icon and some documentation including a PDF version of the Octave Manual and a Quick Reference card .
#Octave vs matlab for mac install
Run the downloaded file to install Octave in your C: drive. Starting the Octave interpreter under Linux is as simple as typing the ’octave’ command. I have been attempting to use the following site:īut have not been very successful so far getting these examples working or as a guide to the Matlab to Octave translation I'm attempting.Īny assistance from Octave experts or those who have gotten computer vision working in both Matlab and Octave would be greatly appreciated.Note for Linux users: Most Linux distributions include Octave as standard and if it is not already installed on your system you can install the Octave package from your installation CDs or the Internet. What other differences should I be aware of to get this Matlab program running under Octave ? Is there an Octave equivalent of the 'vision' object? It is my understanding that 'vision' is part of the Matlab Toolbox, but I am unable to confirm this since I don't have access to Matlab. Obj.blobAnalyser = vision.BlobAnalysis('BoundingBoxOutputPort', true, 'AreaOutputPort', true, 'CentroidOutputPort', true, 'MinimumBlobArea', 400) % (called 'blobs' or 'connected components'), and compute their characteristics, such as area, centroid, and the bounding box. The blob analysis System object is used to find such groups % Connected groups of foreground pixels are likely to correspond to moving objects. Obj.detector = vision.ForegroundDetector('NumGaussians', 3, 'NumTrainingFrames', 40, 'MinimumBackgroundRatio', 0.7) % of 1 corresponds to the foreground and the value of 0 corresponds to the background It outputs a binary mask, where the pixel value % The foreground detector is used to segment moving objects from the background. % Create System objects for foreground detection and blob analysis Obj.maskPlayer = vision.VideoPlayer('Position', ) % and one to display the foreground mask Obj.videoPlayer = vision.VideoPlayer('Position', ) % create two video players, one to display the video, Obj.reader = vision.VideoFileReader('768x576.avi') % create a video file reader

Since I don't have the 'atrium.avi' file used by MathWorks, I changed the VideoFileReader line in the code to use '768x576.avi', which is included with OpenCV ('768x576.avi' is also uploaded to the GitHub repo linked above) Made a separate main.m file to run multiObjectTracking.m I made a GitHub repository for what I have so far, which mostly a re-formatted version of the MathWorks link above:
I'm trying to get this Matlab example from the MathWorks site to work with Octave 4.0.0:
