  • Patent number: 8306353
    Abstract: An information processing apparatus recognizes an object from plural images captured by a image capture device, decides an outline of the recognized object, and calculates average luminances of the inside and the outside of the decided outline. Further, the information processing apparatus determines that a difference between the average luminances of the inside and the outside of the outline is equal to and more than a predetermined value, generates an adjustment image which make gradation increase so that a luminance of any one of the inside and the outside of the outline increases when the difference is equal to and more than the predetermined value, the any one of the inside and the outside of the outline having a lower average luminance than another one. The adjustment image is projected onto the object by a projection device, and then captured by the image capture device.

  • Patent number: 8300969
    Abstract: An edge map creation unit detects an edge intensity of an input image in units of three types of blocks having different sizes. An operation parameter adjustment unit sets initial values of an edge reference value and an extraction reference value on the basis of a dynamic range which is a difference between the maximum and minimum values of the edge intensity. An edge point extraction unit extracts an edge point from the input image on the basis of the edge reference value. Until an extraction amount determination unit determines that the edge point extraction amount is appropriate on the basis of the extraction reference value, the operation parameter adjustment unit repeatedly performs a processing of adjusting the edge reference value, and the edge point extraction unit repeatedly performs a processing of extracting the edge point from the input image on the basis of the adjusted edge reference value.

  • Patent number: 8300882
    Abstract: A watermarking system uses distinct bit patterns to identify a logic 0, a logic 1, and a marker bit, which demarcates segments of logic bit information. Marker bits, which are printed on both foreground and background areas of an image, outline message blocks. In message extraction, a preprocessing step removes any white boarders, identifies the best defined corner of a message block, crops the image, and rotates the image to place the identified corner at the top-left corner. Message extraction scans the rotated image in window segments of increasing size during multiple cycles. During each cycle, if a bit pattern cannot be identified as a data bit, then the size of the examined bit area is increased and rechecked to see it specifically is a marker bit. If no bit information can be definitively identified, then it is assigned a logic bit value based on a 50% random assignment.

  • Patent number: 8285049
    Abstract: A processing device may recognize a number of input handwritten strokes, which may represent a mathematical expression, a chemical formula, or other two-dimensional structure. Rewriting rules of a grammar may be applied to the strokes to produce a number of possible recognition results. Each of the possible recognition results has a respective score based on a sum of rewriting rules applied to the strokes to produce respective ones of the possible recognition results. Input may be provided to identify misrecognized strokes and a correct terminal production, or symbol corresponding to the misrecognized strokes. Strokes may be misrecognized for many reasons, including parsing errors, over-grouping or under-grouping of matrices, and improper placement of a recognized terminal production, or symbol, with respect to a root structure. Correction hints may be leveraged for correcting types of errors mentioned above.
