In this paper, a large-scale underwater image database for underwater salient object detection or saliency detection is presented in detail. This database is called the OUC-VISION underwater image database, which contains 4400 underwater images of 220 individual objects. Each object is captured with four pose variations (the frontal-, the opposite-, the left-, and the right-views of each underwater...
Person re-identification is an important technique towards automatic search of a person's presence in a surveillance video. Two fundamental problems are critical for person re-identification:feature representation and metric learning. At present, there are many methods in the study of person re-identification, which has achieved remarkable results. Due to the difference of the data distribution in...
Traditional theories and methods in 3D reconstruction were all proposed with implicit assumption of air environment. However, underwater environment is different in many aspects. The absorption and scattering effects caused by the suspended particles in the water attenuate the image signal, which disqualifies the traditional reconstruction algorithms. In this paper, we propose a novel method to reconstruct...
Internal waves are a widespread geophysical phenomenon in stratified fluids and studying internal features in the coastal ocean is an important task. Using satellite imagery for studying oceanic internal waves is very popular and studying the low altitude aerial oblique photograph is a new direction. In this paper, we study the images captured from a circling aircraft which track a number of internal...
Photometric Stereo is a popular method for 3D reconstruction from images due to its high level of details handling. However, when it is used in a scattering medium such as lakes and oceans, the recovery result will be negatively impacted by the light absorption, light scattering and the impurities in the water. In this paper, we present a new method to solve the problem of better 3D reconstruction...
Human face analysis is the basis for many other computer vision tasks, such as camera surveillance, entrance authorization and age estimation. With 3D face models, the vision task based on facial analysis can usually achieve a higher accuracy than the 2D cases since it provides more information with the additional dimension. However, most existing 3D face reconstruction methods suffer from complicated...
This paper presents a novel method to conduct camera pose estimation though combining Kinect and Perspective-n-points algorithms. Most existing camera pose estimation methods suffer from the errors caused by inevitable outliers between 2D–3D correspondences. To this end, we propose to use a random down sampling process to deal with outliers in this paper. The proposed method is divided into two main...
Although recognition of vehicle license plate is well studied, characters can be obscured by color stains due to rust, mud, peeling paint or fading colors and become unrecognizable. In this paper, two approaches are presented to remove stains from license plate images by using photometric stereo technique and hole filling algorithm of texture synthesis respectively. The former method extracts height...
