20150110412 | MULTI-BIT ERROR DIFFUSION - The present invention generally relates to systems and methods for error diffusion, e.g., for use in a halftone process. The described techniques are faster than known techniques in that they utilize fewer computations on average. Consequently, the described techniques can be more readily implemented in software, for example, though the described techniques are not limited to software. | 04-23-2015 |
20150088680 | METHODS AND SYSTEMS FOR OPERATING A MARKETPLACE FOR SOFTWARE PRODUCTS - Methods and systems for operating a marketplace. A first price for one or more financial options associated with one or more software products is determined based on a pre-determined set of factors. The one or more financial options include at least an option of buying to lease the one or more software products. The first price for the one or more financial options associated with the one or more software products is modified based on the one or more financial options opted by one or more users. | 03-26-2015 |
20130311403 | CONTONE DOMAIN COLOR PIXEL COUNTING FOR COLOR AREA COVERAGE BASED BILLING - Disclosed herein are a method and a system implementing the method for billing using color pixel counting in documents or image in the contone domain. The method includes using the intensity or density levels (e.g., 0 to 255) for each color of each pixel of interest in the contone domain to calculate one or more probability values that one or more output colorants are provided at its location in the binary domain. The probabilities determined based on the contone color domain data are used to estimate an overall area coverage of color pixels in the document, which can be used to determine a billing structure or cost for outputting the document. | 11-21-2013 |
20130259123 | SYSTEM AND METHOD FOR IDENTIFYING UNIQUE PORTIONS OF VIDEOS WITH VALIDATION AND PREDICTIVE SCENE CHANGES - A computer-based method for generating a compressed data stream, including using a specially programmed computer to: access a first compressed data stream including a first plurality of sequentially arranged frames including respective compressed frame data; access a second compressed data stream including a second plurality of sequentially arranged frames including respective compressed frame data; compare respective compressed data for sequentially matched pairs of frames in the first and second pluralities of frames; select, based on the comparison, common and unique portions in the first data stream; and select, based on the comparison, first and second portions in the second data stream, matched with the common and unique portions, respectively, in the sequence. The first portion has respective compressed frame data equal to the respective compressed frame data for the common portion. The second portion has respective compressed frame data unequal to the respective compressed frame data for the common portion. | 10-03-2013 |
