    Image processing plays an important role in ITS. Since a traffic environment heavily depends on visual information, machine vision is a must in ITS. There are many active research and development programs applying image technologies for ITS. First of all, we need a good and clear image as an input to obtain better image processing results. For this purpose, resolution and dynamic range of an imagi... View full abstract»

    Traffic flow measurement sensors, which measure vehicle velocity and detect traffic accidents, traffic congestion and so on using image processing, have been installed. For the sensors we utilized spatio-temporal images, which are used to process sequential images; as a recognition method for vehicles, we developed Directional-Temporal plane Transform (DTT) which transforms spatio-temporal image t...

    We have developed a lane change aid system (LCAS), which detects vehicles behind in adjacent lanes with multi-line CCD sensors and informs the driver of vehicle location with a head-up display (HUD). Instead of processing camera images directly, a multi-line CCD sensor contains the pairs of line CCDs and measures two-dimensional distance distribution by comparing the brightness on line CCDs.

    Our main objective in this paper is to perform a cartography of a road scene into a reference frame at rest, where 3D measurements delivered by on-board sensors serve as input. The main sensors of our autonomous vehicle are two CCD cameras. Their pictures are combined using stereopsis to generate 3D data. We need dead reckoning to properly associate 3D data among the frames. This necessitates us t... View full abstract»

    A new embedded lossless wavelet-based image coding algorithm called successive partition zero coder (SPZC) which uses both horizontal and vertical bit scanning is proposed. Experimental results show that SPZC outperforms other state-of-the-art coders such as LJEG, SPIHT and CREW etc. In term of coding efficiency by successive partition the wavelet coefficients in the space-frequency domain and non...

    In this paper, an embedded lossless wavelet image coder using multi-partitioning algorithm with bit-trunking (LMP-BT) is described. Without the conventional use of zerotrees analysis, our coder still gives a considerable progressive image transmission (PIT) performance and a superior coding efficiency over others in the literature.

    Most natural images are well modeled as smoothed areas segmented by edges. The smooth areas can be well represented by a wavelet transform with high regularity and with fewer coefficients which requires high-pass filters with some vanishing moments. However for the regions around edges, short highpass filters are preferable. In one recently proposed approach, this problem was solved by switching f... View full abstract»

    We propose a new lossless progressive color coding of color still images. An image is firstly transformed by reversible wavelet transform such as S transform due to progressive transmission of image. And we utilize for an improvement of the compression performance not only for the inter color correlation but also the inter/intra band correlation of the subbands of reversible wavelet transform.

    Natural images are populated with edges characterized by abrupt changes of local statistics. They put severe challenges on probability modeling of image sources. This paper proposes to employ recursive least square (RLS)-based predictive modeling to characterize local statistics for edges. It can be viewed as estimating the covariance matrix from a local causal neighborhood and selecting the MMSE ... View full abstract»

    Common components in recently published lossless image compression algorithms include adaptive prediction, context-based error feedback and adaptive entropy coding. Each component has a number of building blocks. In this paper, we present a new algorithm which uses three new building blocks: an adaptive predictor, a symbol mapping scheme and a context filtering scheme. Experimental results show th...

    LOGO-I (LOw COmplexity LOssless COmpression for Images) is the algorithm at the core of the new ISO/ITU standard for lossless and near-lossless compression of continuous-tone images, JPEG-LS. The algorithm was conceived as a "low complexity projection" of the universal context modeling paradigm, matching its modeling unit to a simple coding unit based on Golomb codes. The JPEG-LS standard evolved ... View full abstract»

    In the present paper we propose lossless compression for RGB color still images which consist of three planes, though many of the proposed techniques for lossless compression are for gray scale images. In the proposed method, we realize effective coding by modifying the prediction errors obtained from each plane. We use color space correlation in modification of prediction errors.

    This paper presents a new volumetric approach to 3D object recognition by using PBSM (Part-Based Superquadric Model). The assembly part object usually can be constructed with the set of volumetric primitives and the relationships of them.

    In this paper, we consider the problem of recognizing 3D object from a single 2D intensity image obtained from unknown position and orientation. We propose the feature set based correspondence algorithm between 3-D model features and 2-D image features, in contrast to the conventional approaches which use a single local feature or fixed number of local features. As a measure of the similarity betw... View full abstract»

    This paper proposes two Hausdorff distance (HD) matching algorithms, in which robust HD measures are implemented in pyramidal structures. By computer simulations, the matching performance of the conventional HD measures and the proposed robust HD matching algorithms using pyramidal structures is compared, with real images which are degraded by noise and occlusions.

    Information contained in video sequences is crucial for an autonomous robot or a computer to learn and respond to its surrounding environment. In the past, robot vision mainly concentrated on still image processing and small "image cube" processing. Continuous video sequence learning and recognition is rarely addressed in the literature due to its high requirement of dynamic processing. In this pa... View full abstract»

    We present an original method for tracking, in an image sequence, complex objects which can be modeled approximately by a polyhedral shape. The approach relies on the estimation of the object image motion as well as the computation of the object pose. The proposed method fulfills real-time constraints along with reliability and robustness requirements. View full abstract»

    The parameters to be estimated in dynamical image analysis are usually restricted to a subset of the Euclidean space. This constraint is often neglected in the design of image analysis algorithms although it allows one to achieve significant improvements. This paper describes an algorithm for the estimation of parameter evolution on manifolds exploiting three sources of information: the manifold g... View full abstract»
