That is not generally possible. It might, however, be possible if you are willing to put restrictions on as to what "text" is for your purposes. Are hieroglyphics "text" or "image" ?

I aim at locating text in an image like a greeting card.I would like to start with a simple thing.Suppressed th background with dct.Now want to extract text features(contrast and homogenity on a 50x50 block).But I don't know this

It is not uncommon for greeting cards to use unusual fonts or to use script fonts; this will make your task more difficult.

Are the greeting cards in any specific language? The extraction process would likely differ between (say) Persian and (say) Old Norse.
