We define and present a new model for semantic video compression and searching, and apply this model to several video genres, with special emphasis on instructional videos. In this model, a semantic distance based on the video genre is computed between adjacent frames in a dynamic video buffer of predetermined size, and redundant "unkey" frames leak from the buffer interior into a data structure "leakage history directed acyclic graph" (LHDAG) which records the relative importance of these frames. What exits the buffer forms a highly compressed video stream consisting of only the most semantically significant video frames, whereas the LHDAG permits efficient semantic exploration of the video interior. This novel hierarchical but context-sensitive data structure LHDAG permits the searching of the video at display rates that are proportional to visual significance, at levels of semantic density selectable by the user. The data structure is simple to create and query, and appears to be more psychologically plausible than more straightforward fixed sampling indexing schemes. We empirically display and mathematically analyze the relationships of the video buffer's leaking rate, buffer size, and exit delay, and demonstrate its performance on several extended videos. The flexibility of the method is indicated by its demonstration on two very different definitions of semantic significance: color similarity, and content ("ink pixel") similarity.

Previous approaches to deformable model shape estimation and tracking have assumed a fixed class of shapes representation (e.g., deformable superquadrics), initialized prior to tracking. Since the shape coverage of the model is fixed, such approaches do not directly accommodate incremental representation discovery during tracking. As a result, model shape coverage is decoupled from tracking, thereby limiting both processes in terms of scope and robustness. We present a novel deformable model framework that accommodates the incremental incorporation during tracking of new geometric primitives (lines, in addition to points) that are not explicitly captured in the initial deformable model but that are moving consistently with its image motion. As these new features are detected via consistency checks, they are added to the model, providing incremental soft constraints on the estimation of its rigid parameters. The consistency checks are based on trilinear relationships between geometric primitives. Consequently, we not only increase both model scope and, ultimately, its higher-level shape coverage, but improve tracking robustness and accuracy, by directly employing the new features in both forward prediction and reconstruction. Our new formulation is a step towards automating model shape estimation and tracking, since it requires significantly reduced initial model hand-crafting. We demonstrate our approach on two separate image-based tracking domains, each involving complex 3D object shape and motion.

JPDAF based HMM for real-time contour tracking

JPDAF based HMM for real-time contour tracking

Tracking objects using multiple cues yields more robust results. The well-known hidden Markov model (HMM) provides a powerful framework to incorporate multiple cues by expanding its observation. However, a plain HMM does not capture the inter-correlation between measurements of neighboring states when computing the transition probabilities. This can seriously damage the tracking performance. To overcome this difficulty, we propose a novel HMM framework targeted at contour-based object tracking. A joint probability data association filter (JPDAF) is used to compute the HMM's transition probabilities, taking into account the intercorrelated neighboring measurements. To ensure real-time performance, we have further developed an efficient method to calculate the data association probability via dynamic programming, which allows the proposed JPDAF-HMM to run comfortably at 30 frames/sec. This new tracking framework can easily incorporate various image cues (e.g., edge intensity, foreground region color and background region color), and also offers an online learning process to adapt to changes in the scene. To evaluate its tracking performance, we have applied the proposed JPDAF-HMM in various real-world video sequences. We report promising tracking results in complex environments.

This paper presents a new 3D reconstruction method of the scoliotic vertebrae of a spine, using two conventional radiographic views (postero-anterior and lateral), and global prior knowledge on the geometrical structure of each vertebra. This geometrical knowledge is efficiently captured by a statistical deformable template integrating a set of admissible deformations, expressed by the first modes of variation in the Karhunen-Loeve expansion of the pathological deformations observed on a representative scoliotic vertebra population. The proposed reconstruction method consists in fitting the projections of this deformable template with the segmented contours of the corresponding vertebra on the two radiographic views. The 3D reconstruction problem is stated as the minimization of a cost function for each vertebra and solved with a gradient descent technique. The reconstruction of the spine is then made vertebra by vertebra. This 3D reconstruction method has been successfully tested on several biplanar radiographic images, yielding very promising results.

Reliable detection and tracking of eyes is an important requirement for attentive user interfaces. In this paper we present a methodology for detecting eyes robustly in indoor environments in real-time. We exploit the physiological properties and appearance of eyes as well as head/eye motion dynamics. Infrared lighting is used to capture the physiological properties of eyes, Kalman trackers are used to model eye/head dynamics, and a probabilistic based appearance model is used to represent eye appearance. By combining three separate modalities, with specific enhancements within each modality, our approach allows eyes to be treated as robust features that can be used for other higher-level processing.

This paper presents a robust and accurate vision-based augmented reality system for surgical navigation. The key point of our system is a robust and real-time monocular vision algorithm to estimate the 3D pose of surgical tools, utilizing specially designed code markers and Kalman filter-based position updating. The vision system is not impaired by occlusion and rapid change of illumination. The augmented reality system superimposes the 3D object wireframe onto the live viewing image taken from the surgical microscope as well as displaying other useful navigation information, while allowing the surgeons to freely change its room and focus for viewing. The experimental results verified the robustness and usefulness of the system, and acquired the image registration error less than 2 mm.

Intelligent rooms equipped with video cameras can exhibit compelling behaviors, many of which depend on object recognition. Unfortunately, object recognition algorithms are rarely written with a normal consumer in mind, leading to programs that would be impractical to use for a typical person. These impracticalities include speed of execution, elaborate training rituals, and setting adjustable parameters. We present an algorithm that can be trained with only a few images of the object, that requires only two parameters to be set, and that runs at 0.7 Hz on a normal PC with a normal color camera. The algorithm represents an object's features as small, quantized edge templates, and it represents the object's geometry with "Hough kernels". The Hough kernels implement a variant of the generalized Hough transform using simple, 2D image correlation. The algorithm also uses color information to eliminate parts of the image from consideration. We give our results in terms of ROC curves for recognizing a computer keyboard with partial occlusion and background clutter Even with two hands occluding the keyboard, the detection rate is 0.885 with a false alarm rate of 0.03.

The general problem of surface matching is considered in this study. The process described in this work hinges on a geodesic distance equation for a family of surfaces embedded in the graph of a cost function. The cost function represents the geometrical matching criterion between the two 3D surfaces. This graph is a hypersurface in 4-dimensional space, and the theory presented herein is a generalization of the geodesic curve evolution method introduced by R. Kimmel et al [10] it also generalizes the 2D matching process developed in [4]. An Eulerian level-set formulation of the geodesic surface evolution is also used, leading to a numerical scheme for solving partial differential equations originating from hyperbolic conservation laws [14] which has proven to be very robust and stable. The method is applied on examples showing both small and large deformations, and arbitrary topological changes.

Using lexical similarity in handwritten word recognition

作者： Park, J Govindaraju, V SUNY Buffalo Dept Comp Sci & Engn CEDAR Buffalo NY 14260 USA

recognition using only visual evidence cannot always be successful due to limitations of information and resources available during training. Considering relation among lexicon entries is sometimes useful for decision making. In this paper, we present a method to capture lexical similarity to lexicon and reliability of a character recognizer which serve to capture the dynamism of the environment. A parameter lexical similarity is defined by measuring these two factors as edit distance between lexicon entries and separability of each character's recognition results. Our experiments show that a utility function considering lexical similarity in a decision stage can enhance the performance of a conventional word recognizer.

Measuring perceptual saliency of regions in a scene is important for determining regions of interest. Color, texture and shape cues are good low-level features for detecting saliency. While self saliency refers to intrinsic attributes of a region, relative saliency is used to measure how salient a region is relative to its surrounding and, thus, needs to be defined within a spatial context. A few spatial context models are investigated in this study. In particular, we propose an auto-scaled, amorphous neighborhood as the context model to obtain reliable measurements of relative saliency features. Comparison of three contest models has shown that the proposed model is capable of generating predicates more consistent with perceived saliency.
