Suppose one image has different objects of different sizes(50pixel,100pixels and 200pixel) in it. How can i Label only those objects which have 100pixels OR Greater than 100pixels & less than 200pixels.

I have labeled all objects in image by using AForge's Connected Components Labeling Method. But I don't know how to do same for specific size objects.

ConnectedComponentsLabeling Labeling = new ConnectedComponentsLabeling();

Bitmap labeledImage = Labeling.Apply(BinaryImage);

int Objects =Labeling.ObjectCount;

Solution

 "// Applying Blob Filter
        BlobsFiltering filter = new BlobsFiltering();
        filter.CoupledSizeFiltering = true;
        filter.MinHeight = 4;
        filter.MinWidth = 4;
        Bitmap FilterImage = filter.Apply(BinaryImage);

        // Counting Ojects
        ConnectedComponentsLabeling Labeling = new ConnectedComponentsLabeling();
        Bitmap labeledImage = Labeling.Apply(FilterImage);
         int TotalNumberofTeeth = Labeling.ObjectCount;

@CarlProthman Yes i have done labeling for all objects using Aforge . I have added its code in question. – hassan May 23 '15 at 17:41
Just did it using Aforge's BlobsFiltering Method. :) – hassan May 23 '15 at 18:36
