Experimental results on defocus, motion, non-blurred images and standard datasets of curved text show that the proposed method outperforms the existing methods.Ĭao S, Ren W, Zuo W, Guo X, Foroosh H (2015) Scene text deblurring using text specific multiscale dicionaries. Further, the proposed method fixes bounding box for each text component based on the nearest neighbor criteria and direction of the text component. Next, Bhattacharyya distance is used to extract symmetry property of texts to remove false text candidates, which provides text components. The proposed method then performs K-means clustering on weighted values of candidate pixels to get text candidates irrespective of blur types. We consider gradient values of each pixel as the weight for the degree of blur. Unlike the existing methods that use deblurring or classifiers, the proposed method estimates degree of blur in images based on contrast variations in neighbor pixels and a low pass filter, which results in candidate pixels for deblurring. In this paper, we present a new method for detecting texts in blurred/non-blurred images. The second part of your requirement is to set the baseline of the text on the right side of the cell.Text detection in video/images is challenging due to the presence of multiple blur caused by defocus and motion. However, remember that 270 degrees is actually the same as -90 (negative 90) degrees.

I can see your confusion, because most places you can specify a rotation allow you to type negative numbers to rotate counter-clockwise.

(Alternatively, you can type Command-Option-B or Ctrl+Alt+B.) The Text Rotation pop-up menu offers four options: 0, 90, 180, and 270 degrees. But I only see an option to rotate text in positive increments!įor those folks who haven’t discovered this yet, you can rotate text inside a table cell by placing the text cursor inside the cell (or selecting one or more cells with the Type tool) and choosing Table > Cell Options > Text. I created a table and want to rotate my text so that is rotated -90 degrees (So that the text is written from bottom to top with the base of the text on the right hand side of the cell).
