How can I make this features extraction code to detect and count

Hi
i need to make this code to detect and track people it extract feaures and combine it i an array
pointrgb=detectSURFFeatures(gryI2,'NumOctaves',1,'NumScaleLevels',3,'MetricThreshold',5000);
[features22, valid_points22] = extractFeatures((gryI2),pointrgb);
[reg,dd] = detectMSERFeatures(rgb2gray(I2),'ThresholdDelta',1,'MaxAreaVariation',1);
[features33, valid_points33] = extractFeatures((gryI2),reg);
comfeat2{k,:}=[features22(:,:);features33(:,:)];
valid_pointscom{k,:}=vertcat(valid_points33,valid_points22);

Hey,
Detection and Tracking are two interdependent processes.
Object Detection and Recognition Code based upon Point Feature Matching can be downloaded from the link attached.
Tracking of an object can be performed using the following links.
Note: Ignore the Augmented Reality (AR) part in the video, object detection and tracking based upon Point Feature Matching.

Although I would suggest you making use of more advanced detection and tracking techniques, such as Motion-Based Multiple Object Tracking, Face Detection and Tracking Using CAMShift, Kanade-Lucas-Tomasi (KLT) point tracking algorithm, Kalman Filtering to predict the location of a moving object and others.
Link to some of the popular techniques are listed below:
