In this paper, a novel non-integer times frame rate up-conversion (NIFRUC) algorithm using reliable analysis of time-domain motion information is proposed. The proposed method can realize frame rate up-conversion (FRUC) of any fractional multiples based on double FRUC. In addition, in order to eliminate motion jerkiness and motion blurring, the proposed method makes full use of motion information to select the inter-frame where movement is faster as the interpolated position and gets interpolated frames by bilateral motion compensation interpolation. Also, in order to obtain more accuracy interpolated positions, a new scene detection scheme as well as the combination of the inter-frame motion speed and inter-frame correlation degree is applied. Experimental results confirm that the proposed method outperforms previous NIFRUC methods in terms of theory analysis, subjective mean opinion score and objective evaluation.
