Abstract


Background prediction correlation between the background pixels to predict the image , but the image noise is independent and can not accurately predict , so the existing background prediction algorithm can not eliminate the noise in the residual plots . To solve this problem , this paper presents a to predict small target detection algorithm from the participation . The algorithm is theoretically possible with any of the existing background prediction algorithm used in combination , to carry the current noise information was forecast points by using the input values ??to correct the predictive value of existing algorithms to improve the accuracy of the forecasts of the background and reduces the noise in the residual plots , and ultimately enable the residual plots, improved signal - to - clutter ratio (SCR) , so as to improve the detection probability . The small target detection algorithms from the participation to predict the theoretical analysis and simulation results show that the small target detection algorithm derived from the participation predicted residual plots SCR than direct use existing algorithms increased 2-3 times .
