1. A computer-implemented method for providing real-time feedback of an estimated quality of a captured final image, the method comprising:
Obtaining, by a portable image capture device, a preliminary image of a document; Calculating, by the at least one computing device, a quality score of the preliminary image; In response to the quality score of the preliminary image exceeding a threshold quality value, taking a first action comprising capturing a final image; and in response to the quality score of the preliminary image not exceeding the threshold quality value, providing feedback to adjust a distance of the portable image capture device from the document being imaged by portable image capture device, Wherein the quality score comprises a framing score, a sharpness score, and a depth variation between the document and a camera that obtains the preliminary image of the document, Wherein the framing score is calculated by measuring a size of a quiet margin in a plurality of zones by using a pixel based technique and a character location technique, and Wherein the sharpness score is calculated in at least one of a vertical and a horizontal direction. |
