  • Patent number: 9720666
    Abstract: The disclosed embodiments provide a system for densely storing strings within the memory of a software program. During operation, the system receives a set of characters to be stored in a string, wherein each character is encoded using a multi-byte public encoding. The system then stores the set of characters in the string at least in part by performing the following steps. The system determines whether every character of the set can be encoded using a first private encoding that consumes less space per character than the multi-byte public encoding. Responsive to determining that every character of the set can be encoded using the first private encoding, the system stores a particular value associated with the first private encoding in a particular field of the string. The system then stores the set of characters in the string in the first private encoding.

  • Patent number: 6683983
    Abstract: A document-inclination detector having a marginal distribution extraction section which extracts a horizontal marginal distribution and a vertical marginal distribution for the document image, a line-direction detection section which recognizes the line direction of each character string of the document image, a marginal distribution correction section which performs a threshold detection on the marginal distribution projected in the line direction, and an inclination detection section which detects the inclination of the line direction of the document image.
