The digital camera captured document images may often be warped and distorted due to different camera angles or document surfaces. A robust technique is needed to solve this kind of distortion. The research on dewarping of the document suffers due to the limited availability of benchmark public dataset. In recent times, deep learning based approach...

... is calculated using three points and they are two end points of the 'headline' and the point on the 'headline' from where the slope changes its sign. Let C r and C s be the curvature of the 'matra/headline' of text lines present in the real image and synthetic image respectively. An example of a 'headline' for a particular text line is shown in Fig. 7 and the 'headline is obtained using the method proposed in [8]. For each image (real and synthetic), we have considered four text lines to evaluate the performance of the proposed method. Two text lines from the top and two from the bottom of the image. The length of the each considered text line is greater than 80% of the longest text ...

Mechanical image stabilization using actuated gimbals enables capturing long-exposure shots without suffering from blur due to camera motion. These devices, however, are often physically cumbersome and expensive, limiting their widespread use. In this work, we propose to digitally emulate a mechanically stabilized system from the input of a fast un...
