In order to improve the detection quality of direction of the objects moving in fixed direction from blurred image

In this paper

we propose a new algorithm for detection of moving direction

which is based on the pre-processing of spectrum image. First

the spectrum image of motion-blur image is transformed twice with Fourier logarithmic to meet refinment of bright lines. Second

with the previous spectrum as input

the image is bi-value processing with slipping neighbour operation

eliminating image noise and cross bright line. Finally

the pre-processed image is performed with Radon transform

detecting image linear characteristic

and mapping the detection results into direction of the blurred image. The experimental results show as below: 1) in different fuzzy scale and direction of the environment

the proposed algorithm can always limit the movement direction detection error under 0.5°;2) our algorithm can obtain better movement direction detection than other related algorithms.
