Abstract: Methods and systems for correcting depth irregularities in a three-dimensional scanned model. In particular, one or more embodiments obtain depth data and color data for an object using a depth scanner and a color scanner, respectively. One or more embodiments identify, based on edge information in the color data, regions that have no depth data that are part of the object. One or more embodiments then correct the depth frame by assigning depth data to the identified regions based on a gradient of depth data from areas near the identified regions. The methods and systems use the corrected depth data to generate a corrected three-dimensional model of the object.

Abstract: Techniques are disclosed for noise reduction and color smoothing of scanned 3D models for 3D printing. An anisotropic box kernel variant of a bilateral filter is applied to each vertex of a 3D mesh model, where the vertices contain color information. With bilateral filtering, the color at a given vertex is, under certain conditions, replaced by a Gaussian weighted average of colors of neighboring vertices. The weighting is a function of a geometric distance between vertices. The direction of traversal is limited towards neighboring vertices where a color mismatch is a color difference larger than the threshold value. The color of a neighboring vertex is rejected if the vertex normals differ from by a large angle. The weighted average of colors of the neighboring vertices is also rejected if the given vertex lies in a region where the color match/mismatch ratio is low at the end of the traversal.

Abstract: A computer implemented method and apparatus for automatically adding utility holes to printable 3D models by accessing a digital representation of a 3D model; accessing specifications that define the geometry of a utility hole to be included with the 3D model; performing a heuristic evaluation of the digital representation of the 3D model to determine one of one or more possible placements of the utility hole to be included with the 3D model as a placement for the utility hole; modifying the digital representation of the 3D model so as to include the utility hole at the placement; and providing a modified digital representation of the 3D model for printing.

Abstract: Green printing is utilized to repurpose a document. An indication is received that a printout of a document from a printer has been requested. The document has content with a format that would result in a first quantity of pages being printed. The content is grouped into one or more regions. Further, one or more transformations are applied to the content for each region such that the printer prints the document with the content in a transformed format that results in a second quantity of pages being printed without falling below a predetermined readability threshold. The second quantity of pages is less than the first quantity of pages. Further, the one or more transformations being applied to the document may result in a second quantity of ink being utilized to print the document such that the second quantity of ink being less than the first quantity of ink.

Abstract: A presentation document is repurposed to save paper and ink. An indication that a printout of a presentation document from a printer has been requested is received. The presentation document has content with a format that would result in a first quantity of pages being printed. The content has a plurality of slides and a plurality of shapes. Further, the presentation document is preprocessed to acquire data associated the presentation document. Group shaping is also performed to group the plurality of shapes into one or more groups based on shapes that have to be transformed together. Further, content transformation is performed to generate transformed content. In addition, a content re-layout is performed to determine placement of the transformed content.

Abstract: A spreadsheet is repurposed to save paper and ink. An indication that a printout of a spreadsheet from a printer has been requested is received. The spreadsheet has content with a format that would result in a first quantity of pages being printed. Further, a printable range for the spreadsheet is determined. In addition, an overlap analysis of the spreadsheet is performed to determine if any of the plurality of shapes in the spreadsheet overlap one another. Each print zone is isolated in the spreadsheet. The print zone includes a group of cells. Each print zone is transformed into a transformed print zone. Further, a green spreadsheet is generated, without falling below a predetermined readability threshold, based on each transformed print zone such that the green spreadsheet has a second quantity of pages that is less than the first quantity of pages.
