<br />The code runs on Windows/Linux with MATLAB R2011-2013.
<br />A test sequence "test.avi" is included so you can simply run Demo.m
<br />Object center locations are saved in output.mat
<br />----------------------------------------------------------------------
<br />This code presents an object tracking method based on the object and background colors. A three dimensional feature vector is used to describe color feature (R, G, B) of each pixel. A quantized histogram of that feature value of pixels on the selected object and a quantized histogram of pixels from the neighborhood surrounding the object are developed. The RGB based joint probability density function of the selected object region and that of a neighborhood surrounding the object are used to separate object from background. An adaptive color model of separated object is developed to detect the object in subsequent frames while Mean-shift procedure is used to track the object.

<br />Even if MATLAB is able to handle this problem properly, it could be useful to determine the end of line for a text file. For exemple when reading the file with the "fread" function and its argument "skip" (constant number of characters per column).</p>
<p>ostxtfile uses the buitlin function "fgets" to return the native operating system on which the file was created. So it should works on any system and on any version of MATLAB.</p>Jerome Briothttp://www.mathworks.com/matlabcentral/profile/authors/492531-jerome-briotMATLAB 8.5 (R2015a)falsetag:www.mathworks.com,2005:FileInfo/527832015-09-01T12:50:21Z2015-09-01T12:50:21Zconvert date with format of yyyymmdd to doy (decimal day of year)a function converting date to doy<p>Converting date to decimal day of the year (doy) or the opposite is a general practice for meteorologists, ecologists, hydrologists, as they often need to deal with time series of meteorological variables, hydrological data, etc. These two files are therefore generated to help covert date with the format of yyyymmdd(i.e., year with four digits, month with two digits, day with 2 digits) to doy, and convert doy of a year into date with month and day.</p>Quan Zhanghttp://www.mathworks.com/matlabcentral/profile/authors/6849448-quan-zhangMATLAB 7.14 (R2012a)Aerospace ToolboxMATLABfalsetag:www.mathworks.com,2005:FileInfo/527802015-09-01T00:27:20Z2015-09-01T00:27:20ZBeta-Bernoulli ClassifierDemonstration example of the Beta-Bernoulli Classifier<p>This code provides a demonstration example of the Beta-Bernoulli Classifier.
