Proposed method improves the retrieval result as compared with the standard LBP also improves the average precision rate, however the algorithmic procedure much complex than LBP and LTP.

The previously declared Local Binary Pattern LBP can able to encode the images with two distinct values and Local Ternary Pattern LTP can encode images with only three distinct values but the LTrP encoded the images with four distinct values as it is able to extract more detailed information.

The second order derivatives can be defined as a function of first order derivatives. Due to the effectiveness of the proposed method, it can be also suitable for other pattern recognition applications such as face recognition, finger print recognition, etc.

Let be discuss about the performance evaluation. Here, horizontal and vertical pixels have been used for derivative calculation. It can automatically search the desired image invariantss the huge database. Resulting pixel value is summed for the LBP number of this texture unit.
