For pattern recognition you should be creating feature vectors rather than submitting the scaled-down image directly.

Try imresize() function in the Image Processing Toolbox:
smallImage = imresize(binaryImage, [32, 32], 'Nearest');
Obviously you will have loss of data. Not sure how you define "significant". I guess if your algorithm can still recognize what's in the scene, despite being smaller, then it's not significant.

That would get the main axis going through the body.
I don't know much about this field, but there is a whole field of image processing involved in looking at silhouettes of human bodies or body parts. Go here to VisionBib to find all the papers on it.
