Sketch Interpretation and Refinement Using Statistical Models [article]

Saul Simhon, Gregory Dudek

Our approach is based on a Hierarchical Hidden Markov Model. We present a two level hierarchy in which the refinement process is applied at: the curve level and the scene level.  ...  A user can draw a coarse sketch and the system would automatically augment the shape, thickness, color and surrounding texture of the curves making up the sketch.  ...  Although almost everyone can sketch out a crude illustration, only a few of us have the artistic talent and patience to draw the refined details we wish to depict.  ...

Towards a mathematical theory of primal sketch and sketchability

We then propose a primal sketch model that integrates the two models and, in addition, a Gestalt field model for spatial organization.  ...  The model can be used to learn a dictionary of image primitives, or textons in Julesz's language, for natural images.  ...  Descriptive image models interpret images at the signal level, e.g., raw pixel intensities, by pooling statistics using features, e.g., filters.  ...

A subsequent post-process procedure with multi-label graph cuts further refines the segmentation and labeling result. We validate our proposed method on two sketch datasets.  ...  We train a deep neural network to transfer existing segmentations and labelings from 3D models to freehand sketches without requiring numerous well-annotated sketches as training data.  ...  As suggested by Isola et al., 19 during testing, we use batch normalization with the statistics of the testing data batch (freehand sketches) instead of the accumulated statistics of the training data  ...

We wish to sketch the picture that quantum mechanics, as we know it, should be looked upon as a powerful mathematical tool to handle statistical features of our theories.  ...  If the dynamical equations are too complex to allow us to solve them, the quantum statistical approach may be the only option we have.  ...  There are however other reasons why the most explicit model constructions sketched here are not, or not yet, sufficiently refined to serve as models where we can explain all typically quantum mechanical  ...

The user can add detailed geometry and textures through sketches as well. This is possible using databases that match partial sketches to models of detailed geometry and textures.  ...  As the sketch is being drawn, our system periodically interprets its 2.5D geometry by identifying new junctions, edges, and faces, and then analyzing the extracted topology.  ...  ACKNOWLEDGMENTS We would like to thank the reviewers for their valuable feedback and Crystal Digital Technology Co., Ltd. for providing the 3D models of detailed geometries used in our database.  ...

Compared with the existed primal sketch extraction methods, our method is fully driven by the image data, and it needs neither to choose filters nor to learn the image bases.  ...  In this paper, we propose a novel method to obtain the primal sketch of natural images by integrating empirical mode decomposition (EMD) techniques and image gradient. 2D EMD approach can decompose the  ...  One is zero-crossing [1~3] and the other is primal sketch model based on statistics [4, 5] . The key point of zero-crossing method is how to choose spatial constant of filter.  ...

The resulting methodology can be repeated with other drawings to obtain a set of sketches and segmentation data which could be used as a benchmark for segmentation algorithms, to evaluate their capability  ...  In this paper, we study the segmentation of sketched engineering drawings into a set of straight and curved segments.  ...  The Spanish Ministry of Science and Education and the European Union partially supported this work: DPI2007-66755-C02-01 (CUESKETCH: multi-agents based recognition of ideation sketches).  ...
