In this paper, a new method of detecting text regions from video sequences, without prior knowledge such as font, color, size of characters is proposed. By analyzing the characteristics of text regions in video sequences, we found that text regions include both horizontal and vertical edges simultaneously, while background regions do not. Therefore, In order to detect text regions accurately, the...
In this paper we propose an effective video dehazing technique to reduce flicker artifacts by using adaptive temporal average. When applying a dehazing method for still image to a video sequence, flicker artifacts may occur because atmospheric values calculated independently for each frame change frame by frame. In existing approaches flicker artifacts are reduced by yielding highly correlated transmission...
