Is it possible to remove small patches of an image using Blob analysis?
===

i am wondering about what exactly a blob is? Is it is possible to reduce background noises in the image? Or is it possible to find largest region in and image, more epecifically if an image contains hand and head segments only then is it possible to separete hand or head regions only?? **If this is possible then it is also possible to select boundary having larger contours, while eliminating small patches in the image** ??
