Advances in video technology have enabled its wide adoption in the auto industry. Today, many vehicles are equipped with backup, front-looking, and side-looking cameras that allow the driver to easily monitor traffic around the vehicle for enhancing safety. One difficulty with performing automated image analysis using a vehicle's onboard video has to do with the significant lens distortion of these...
Advances in video technology have enabled its wide adoption in the auto industry. Today, many vehicles are equipped with backup, front-looking, and side-looking cameras that allow the driver to easily monitor the traffic around the vehicle for enhanced safety. This paper reports our research on evaluating many existing object tracking techniques, and proposes a new tracker design and its application...
This paper proposes a new intelligent surveillance system for parking lot management in underground environments. The feature based image stitching and image blending techniques are used to let video streams captured by multiple cameras be fused into single output whose blind area could be easily seen through. Such system allows that anyone can immediately understand what is going on in the whole...
The goal of the project is to design intelligent and robust image-processing and augmented-reality algorithms for driver assistance and enhanced vehicular safety. In particular, the focuses were two-fold: (1) realizing the abilities to identify and localize in a vehicle''s on-board video the sweeping windshield wipers during raining days and (2) designing and implementing an in-painting technique...
This paper proposes a new algorithm to eliminate the wiper interference in a vehicle's onboard video to improve the detection rate of vision-based Advanced Driver Assistance Systems (ADAS), such as Forward Collision Warning (FCW) Systems. During raining days, the windshield wipers periodically and partially block the appearance of obstacles on the road that are to be detected in these early warning...
This paper proposes a new vehicle blind spot elimination system which utilizes the on-board videos captured from other vehicles and the host vehicle. Such information is exchanged by WAVE/DSRC devices to achieve collaborative safety. The preceding vehicle which fully or partially blocks the field of view of the host vehicle could be translucentized in the video captured by the host vehicle and the...
This paper proposes a monocular vision-based obstacle detection algorithm for parking assistance applications of advance safety vehicle by a rear camera. In order to efficiently detect various moving and stationary obstacles behind the vehicle, the feature of corner into the rear obstacles is firstly estimated by the Features from Accelerated Segment Test (FAST) corner detection methods. Then, the...
This paper presents a new vision-based vehicle detection method for Forward Collision Warning System (FCWS) at nighttime. Also, lane detection is performed for assistance. To effectively extract the bright objects of interest, an essential image preprocessing including the tone mapping, contrast enhancement and adaptive binaryzation is applied in the nighttime road scenes. The characteristics of taillights...
This paper proposes a novel fast dehazing method based on dark channel prior. The dark channel prior is the phenomenon about normal outdoor images containing at least one low energy pixel around a block among three channels. It helps roughly estimating the air mediums thickness, which decreases the scene transmission. We propose a variation of optical model whose single atmospheric attenuation coefficient...
Marketing channel as the downstream end of a supply chain assumes a prominent role for delivering company's offerings to customers, meeting their demands, and creating cash flow for company. To ensure better customer relationship and secure more market power, retailing stores make efforts to differentiate themselves by introducing private brand products in addition to existing national brands. Globalization...
Innovation in both technology and service play a crucial role in enhancing consumers' living standard and companies' growth. Outcomes of Innovation often go premature due to failing to cross the chasm of adoption. Literature in this domain takes the positive perspective to describe and explain the phenomena, however, scarcely provides any solution. This study from a normative marketing perspective...
A novel image compression scheme that takes advantages of side-match vector quantization (SMVQ) and search-order-coding (SOC) algorithm is proposed in this article. In the proposed scheme, the image to be compressed is firstly encoded into an index table by applying the traditional SMVQ compression technique. Then, the index table of image is further compressed based on the ordinary SOC algorithm...
Many attempts to bridge innovation and creating market opportunity fail due to a company's incompetence to cross the chasm-the diffusion transition between the embryonic market where customers are innovators/early adopters and the profitable mass market where customers are early majority/later majority. However, the extant body of literature address the why but not the how. This paper thus presents...
Effects of current stressing of 6.5 × 103 A/cm2 on the eutectic SnBi solder joint at 70°C were investigated. The Bi segregation at the anode side was found, and the Bi segregation layer grew with the increasing stressing time. The Bi segregation may result in the strength reduction and the more serious Joule heating due to the brittleness and the higher resistivity of Bi, respectively. Effects of...
