Abstract
A reading machine has processing for detecting common text between a pair of individual images. The reading machine combines the text from the pair of images into a file or data structure if common text is detected, and determines if incomplete text phrases are present in the common text. If incomplete text phrases are present, the machine signals a user to move an image input device in a direction to capture more of the text.
Claims22
A computer program product tangibly embodied on a computer readable storage device for causing a computing device to examine multiple images, comprising instructions for causing the computing device to:
- receive text provided from performing optical character recognition on a pair of images captured by an image input device;
- detect common text in text strings
- to combine the text from the pair of images based on the common text that corresponds to overlap of text;
- determine if incomplete text phrases are present in the combined text, and when incomplete text phrases are present,
- determine a direction to move the image input device to capture more of the text in one of the pair of images;
- and
- signal a user to move the image input device that captures the pair of individual images in the determined direction to cause the image input device to capture in a new image more of the text that is in one of the pair of images.
A method comprising:
- receive text provided from performing optical character recognition on a pair of images captured by an image input device;
- detecting common text
- to combine the text from the pair of images based on the common text that corresponds to overlap of text;
- determining if incomplete text phrases are present in the combined text, and when incomplete text phrases are present;
- determining a direction to move the image input device to capture more of the text in one of the pair of images;
- and
- signaling a user to move the image input device in a direction to capture more of the text.
A reading machine comprises:
- a computing device;
- an image input device coupled to the computing device for capturing images;
- and
- a computer program product residing on a computer readable medium comprising instructions for causing the computing device to:
- receive text provided from performing optical character recognition on a pair of images captured by the image input device;
- detect common text in text strings
- to combine the text from the pair of images based on the common text that corresponds to overlap of text;
- determine if incomplete text phrases are present in the combined text, and when incomplete text phrases are present,
- determine a direction to move the image input device to capture more of the text in one of the pair of images;
- and
- signal a user to move the image input device in the determined direction to capture more of the text in one of the images.
