Traffic light detection has a significant role in every driver assistance system (DAS). Using the information of recognized traffic signals, a DAS provides safe navigating suggestions to drivers. In this paper, we focus on horizontal traffic light formats, which are popular in South Korea, North American and most European countries. Despite their different shapes and sizes, we group important traffic light signals into six categories: red, yellow, green, green-turn, red-turn and no signal. This paper proposes a method to localize all traffic light positions in the current scene; and identify the main ones from them. To detect and classify traffic signals, we use YOLOv4, which is the most recent deep learning framework. Next, based on the relation of detected traffic lights, our system removes irrelevant signals. Finally, with the optimized set of detected traffic lights, we identify the main signal for the whole scene. Experiments were conducted on two large datasets captured in Seoul Korea containing both highways and urban areas. The results achieved 95% accuracy at 30FPS.

As Taiwan enters an aging society, the number of disabled people increases accordingly, resulting in a growing burden for longterm care and family care managements. We propose an eye-hand integration system with an infrared sensor attached to the end of the arm. Not only can the accuracy of feeding be controlled, but also the position of the spoon/claw can be micro-controlled while picking up food as cleanly as possible. It is more intelligent than other feeding robot arms. It can automatically adjust the position of the head and face of users of different sizes and orientations. As long as the base of the arm is placed close to the head of the bed, feeding the arm can serve the user without special posture adjustment. At the same time, the users' head are mounted with a laser light and a camera which serves as a lighting sources on multiple dark areas on the food table. Given the lighted instructions, the robot arm is guided to different food plate. Disabled patients can then freely choose the order of eating and enjoy the quality of life. We report the details of constructing such system and presents the imageprocessingalgorithms for laser light selection operations.

Owing to flexibility of Unmanned Aerial Vehicles (UAVs) and high efficiency of imageprocessing technology, the combined systems become increasingly popular and important in the smart city operations. However, the application scenarios of this technology, especially on the traffic system prediction and multi-vehicle information extraction, still need to be explored. Besides, vehicle's detailed attributes need to be considered when building models. The smart traffic system can be broadly divided into two parts, traffic facilities (e.g. traffic signals, signs and sensors) and participants (e.g. vehicles and pedestrians). Many related works are presented about traffic parameters measurements using UAVs. In this paper, the prediction and traffic signal system analysis through different categories of vehicles' dynamic characteristics extracted from UAVs is presented. The motivation and related work is introduced. A stochastic process framework is presented for multi-vehicle speed extraction and signal transition time distributions at a signalized intersection. Detection and tracking methods/algorithms are proposed. To verify the mathematical model, the experimental data is collected at one intersection, in the city of Singapore during peak hours. After data collection, aerial images are processed to extract information. The regression method and processed parameters help to fit the required dynamic functions for different types vehicles. The estimated distributions reflect the traffic signal transition time provided by ground truths nicely. Moreover, the future research is presented on enhancing the system prediction accuracy and robustness.
Modern communication between built environment professionals are governed by the effective exchange of digital models, blueprints and technical drawings. However, the increasing quantity of such digital files, in conj...

Correlation filtering is a fast and robust signal detection and processing algorithm. However, in the field of images processing, scale and rotation variation are important issues for correlation filtering algorithms. This paper proposes a detection method based on correlation filtering, which uses axis of symmetry and circumscribed rectangles to estimate the rotation and scale of the target. Firstly, using the HSV model to separate the colors to be found in the original image. Then, the axisymmetric shell intersection method is proposed to solve the symmetry axis and the circumscribed rectangle of the object. Finally, a correlation filter is used to solve all the areas that are likely to be objects. The response value, the position with the highest response value is the object position. The algorithm performs experiments on a set of artificially calibrated image sequences. Experiments show that this method can achieve better detection results when the number of training samples is small.

This paper presents a surveillance system that is capable of transmitting its geo location and the information from real time images to a central unit in no network zone. The system is further configured for using imageprocessing and machine learning algorithms to deduce any suspicious object from the captured image. Thereby, the system is helpful in identifying threats in all kind of weather conditions on land and in oceans. The system is very efficient, cost effective and is simple in design. Once the threat is identified, the system transmits the information to the central unit through the LoRa by using certain communication protocols. Compared to existing devices, this system has the potential to reduce causalities by enhancing navigational and observational features in the surveillance sector.

With the explosion of information, characteristics of increasingly complex data, the use of traditional methods in data processing has proved ineffective. Computer applications are increasingly becoming important and essential in many areas such as biology, medicine, psychology, economics, imageprocessing and many other disciplines. A variety of multi-spectral satellite image classification, clustering algorithms have been developed and applied to analyze the surface of the earth. In this paper, we propose a novel semi-supervised possibilistic fuzzy c-means clustering on spatial-spectral distance (SPFCM-SS) for multi-spectral image land-cover classification by the extension of the possibilistic fuzzy C-means (PFCM) algorithm, in which spectral information and spatial information of the pixels are used coupled with labelled data to increase the accuracy of clustering results when the data structure of input patterns is non-spherical and complex. Experiments were performed for multi-spectral satellite image data and clustering efficiency indexes were used to compare the performance of the proposed algorithm with other similar algorithms.
