{"input": "This paper presents an algorithm for computing optical flow, shape, motion, lighting, and albedo from an image sequence of a rigidly-moving Lambertian object under distant illumination. The problem is formulated in a manner that subsumes structure from motion, multi-view stereo, and photo-metric stereo as special cases. The algorithm utilizes both spatial and temporal intensity variation as cues: the former constrains flow and the latter constrains surface orientation; combining both cues enables dense reconstruction of both textured and texture-less surfaces. The algorithm works by iteratively estimating affine camera parameters, illumination, shape, and albedo in an alternating fashion. Results are demonstrated on videos of hand-held objects moving in front of a fixed light and camera.", "output": {"entities": {"generic": [{"text": "algorithm", "start": 23, "end": 32}, {"text": "problem", "start": 190, "end": 197}, {"text": "algorithm", "start": 326, "end": 335}, {"text": "cues", "start": 394, "end": 398}, {"text": "former", "start": 404, "end": 410}, {"text": "latter", "start": 435, "end": 441}, {"text": "cues", "start": 489, "end": 493}, {"text": "algorithm", "start": 571, "end": 580}], "task": [{"text": "computing optical flow, shape, motion, lighting, and albedo", "start": 37, "end": 96}, {"text": "dense reconstruction of both textured and texture-less surfaces", "start": 502, "end": 565}], "material": [{"text": "image sequence", "start": 105, "end": 119}, {"text": "rigidly-moving Lambertian object", "start": 125, "end": 157}, {"text": "motion", "start": 68, "end": 74}, {"text": "multi-view stereo", "start": 261, "end": 278}, {"text": "photo-metric stereo", "start": 284, "end": 303}, {"text": "videos of hand-held objects", "start": 726, "end": 753}], "other_scientific_term": [{"text": "distant illumination", "start": 164, "end": 184}, {"text": "spatial and temporal intensity variation", "start": 350, "end": 390}, {"text": "flow", "start": 55, "end": 59}, {"text": "surface orientation", "start": 453, "end": 472}], "method": [{"text": "estimating affine camera parameters, illumination, shape, and albedo", "start": 602, "end": 670}]}, "relations": {"used_for": [{"head": {"text": "algorithm", "start": 23, "end": 32}, "tail": {"text": "computing optical flow, shape, motion, lighting, and albedo", "start": 37, "end": 96}}, {"head": {"text": "image sequence", "start": 105, "end": 119}, "tail": {"text": "algorithm", "start": 23, "end": 32}}, {"head": {"text": "spatial and temporal intensity variation", "start": 350, "end": 390}, "tail": {"text": "algorithm", "start": 326, "end": 335}}, {"head": {"text": "former", "start": 404, "end": 410}, "tail": {"text": "flow", "start": 55, "end": 59}}, {"head": {"text": "latter", "start": 435, "end": 441}, "tail": {"text": "surface orientation", "start": 453, "end": 472}}, {"head": {"text": "cues", "start": 489, "end": 493}, "tail": {"text": "dense reconstruction of both textured and texture-less surfaces", "start": 502, "end": 565}}, {"head": {"text": "estimating affine camera parameters, illumination, shape, and albedo", "start": 602, "end": 670}, "tail": {"text": "algorithm", "start": 571, "end": 580}}], "feature_of": [{"head": {"text": "rigidly-moving Lambertian object", "start": 125, "end": 157}, "tail": {"text": "image sequence", "start": 105, "end": 119}}, {"head": {"text": "distant illumination", "start": 164, "end": 184}, "tail": {"text": "rigidly-moving Lambertian object", "start": 125, "end": 157}}], "conjunction": [{"head": {"text": "motion", "start": 68, "end": 74}, "tail": {"text": "multi-view stereo", "start": 261, "end": 278}}, {"head": {"text": "multi-view stereo", "start": 261, "end": 278}, "tail": {"text": "photo-metric stereo", "start": 284, "end": 303}}, {"head": {"text": "former", "start": 404, "end": 410}, "tail": {"text": "latter", "start": 435, "end": 441}}], "hyponym_of": [{"head": {"text": "former", "start": 404, "end": 410}, "tail": {"text": "cues", "start": 394, "end": 398}}, {"head": {"text": "latter", "start": 435, "end": 441}, "tail": {"text": "cues", "start": 394, "end": 398}}]}}, "schema": []} {"input": "Past work of generating referring expressions mainly utilized attributes of objects and binary relations between objects.

Previous approaches detect and describe features at different scale levels by building or approximating the Gaussian scale space of an image. However, Gaussian blurring does not respect the natural boundaries of objects and smoothes to the same degree both details and noise, reducing localization accuracy and distinctiveness. In contrast, we detect and describe 2D features in a nonlinear scale space by means of nonlinear diffusion filtering. In this way, we can make blurring locally adaptive to the image data, reducing noise but retaining object boundaries, obtaining superior localization accuracy and distinctiviness. The nonlinear scale space is built using efficient Additive Operator Splitting -LRB- AOS -RRB- techniques and variable con-ductance diffusion. We present an extensive evaluation on benchmark datasets and a practical matching application on deformable surfaces.

reconstruction on demand by tensor voting, or ROD-TV. ROD-TV simultaneously delivers good efficiency and robust-ness, by adapting to a continuum of primitive connectivity, view dependence, and levels of detail -LRB- LOD -RRB-. Locally inferred surface elements are robust to noise and better capture local shapes. By inferring per-vertex normals at sub-voxel precision on the fly, we can achieve interpolative shading. Since these missing details can be recovered at the current level of detail, our result is not upper bounded by the scanning resolution. By relaxing the mesh connectivity requirement, we extend ROD-TV and propose a simple but effective multiscale feature extraction algorithm. ROD-TV consists of a hierarchical data structure that encodes different levels of detail. The local reconstruction algorithm is tensor voting. It is applied on demand to the visible subset of data at a desired level of detail, by traversing the data hierarchy and collecting tensorial support in a neighborhood.

In order to deal with ambiguity, the MORphological PArser MORPA is provided with a probabilistic context-free grammar -LRB- PCFG -RRB-, i.e. it combines a ``conventional'' context-free morphological grammar to filter out ungrammatical segmentations with a probability-based scoring function which determines the likelihood of each successful parse. Consequently, remaining analyses can be ordered along a scale of plausibility. Test performance data will show that a PCFG yields good results in morphological parsing.

We formulate the proposal generation problem as a generative proba-bilistic model such that object proposals of different shapes -LRB- i.e., sizes and orientations -RRB- can be produced by locating the local maximum likelihoods. The new approach has three main advantages. First, it helps the object detector handle objects of different orientations. Second, as the shapes of the proposals may vary to fit the objects, the resulting proposals are tighter than the sampling windows with fixed sizes. Third, it avoids massive window sampling, and thereby reducing the number of proposals while maintaining a high recall. Experiments on the PASCAL VOC 2007 dataset show that the proposed OOP outperforms the state-of-the-art fast methods. Further experiments show that the rotation invariant property helps a class-specific object detector achieve better performance than the state-of-the-art proposal generation methods in either object rotation scenarios or general scenarios.
