This paper proposes the use of a vector of color histogram

peaks a n efficient and effective way for many image indexing

problems. It shows that histogram peaks are more stable than

general histogram bins when there are variation of scale and/or scale.

We also introduce the structure of a room recognition system which

applies this indexing technique to omni-directional images of rooms.

Experimental results shows that using only peaks leads to significantly

less time and storage demands an still provides  recognition

rates across a database of hundreds of rooms.-This paper proposes the use of a vector of color histogram
