7.Application of image processing techniques for the extraction of vehicle number plates over ARM target board

Correct recognition of vehicles violating traffic rules and regulations is a major challenge in the present complex traffic environment. Automatic Number Plate Recognition (ANPR) systems plays an important role in the detection of such events. ANPR systems are typically standalone systems using the capabilities of embedded processors for correct recognition. The limited processing capabilities hinders the efficient determination of location of number plates in such images satisfying the real time criteria. This paper presents an adopted method for the image preprocessing, image detection and extraction of standardized white background vehicle number plates. Application of suitable Gaussian Filters along with other image preprocessing techniques, Binary jumps and Image differencing techniques have been carried out in this work.

9.A cloud computing-based image codec system for lossless compression of images on a Cortex-A8 platform

Aimed to provide an efficient architecture for the storage and processing of medical images, a cloud computing-based system is proposed in this paper. In addition, with the highly increased computational ability of embedded systems, an ARM-based Cortex-A8 embedded platform is applied in the proposed architecture as the kernel for the lossless compression, decompression, as well as the processing of medical images. All the images generated are first sent to the embedded platform for lossless compression before stored in the image database server. On the other hand, images are retrieved and first sent to the platform for decompression, and then transmitted via the network to the client for viewing purpose. In the proposed system, the decompressed images are transmitted with the protocol of HTTP, which means only a browser is needed for the client. Moreover, the client can perform image processing, e.g, image sharpening and histogram equalization with respect to the selected image in the browser, no other application program is required. As no other application program is required for the client other than the browser, the proposed system architecture is very easy to maintain with, and the computational burden traditionally imposed on the client can be quite alleviated. Furthermore, the coding algorithm used is very effective and efficient for the lossless compression of images as we will see in the experiment. The cloud computing-based architecture in conjunction with the high efficient coding algorithm make the proposed system very feasible for practical usage.

13.On-line monitoring system of insulator leakage current based on ARM

A ceramic insulator has an excellent anti-pollution performance, but sometimes flashover occurs on it and then the outage of power network follows. This paper analyzes the formation mechanism of flashover and the result is that the RMS of leakage current(LC) and discharge pulses reflect the contamination severity approximately. This shows that to a large extent the flashover accident can be avoided by means of monitoring the leakage current value and the discharge pulses. Existing monitoring device for contaminated insulators inspects either leakage currents or discharge pulses, also, it is difficult to meet the requirements of the client for low-power consumption, low cost and high reliability. In this paper, a novel low-power and low-cost online monitoring system is presented, which is based on ARM Cortex-M and Zigbee wireless network. In addition, the monitoring system not only acquires the leakage current and discharge pulses of insulator strings, but also measures the environmental temperature and humidity and then comprehensively analyzes the severity of insulator pollution. After that the results will be displayed on the LCD or sent to the control center through the Zigbee network. Tests show that the monitoring system has good accuracy and good practical performance.
Brain EEG signal processing for controlling a robotic arm
Researchers recently proposed new scientific methods for restoring function to those with motor impairments. one of these methods is to provide the brain with a new non-muscular communication and control channel, a direct Brain-Machine Interface (BMI). This paper presents a Brain Machine Interface (BMI) system based on using the brain electroencephalography (EEG) signals associated with 3 arm movements (close, open arm and close hand) for controlling a robotic arm. Signals recorded from one subject using Emotive Epoc device. Four channels only were used, in our experiment, AF3, which located at the prefrontal cortex and F7, F3, FC5 which located at the supplementary motor cortex of the brain. Three different techniques were used for features extraction which are: Wavelet Transform (WT), Fast Fourier Transform (FFT) and Principal Component Analysis (PCA). Multi-layer Perceptron Neural Network trained by a standard back propagation algorithm was used for classifying the three considered tasks. Classification rates of 91.1%, 86.7% and 85.6% were achieved with the three used features extraction techniques respectively. Experimental results show that the proposed system achieved high classification rates than other systems in the same application.

Embedded System for Biometric Online Signature Verification
This paper describes the implementation on field-programmable gate arrays (FPGAs) of an embedded system for online signature verification. The recognition algorithm mainly consists of three stages. First, an initial preprocessing is applied on the captured signature, removing noise and normalizing information related to horizontal and vertical positions. Afterwards, a dynamic time warping algorithm is used to align this processed signature with its template previously stored in a database. Finally, a set of features are extracted and passed through a Gaussian Mixture Model, which reveals the degree of similarity between both signatures. The algorithm was tested using a public database of 100 users, obtaining high recognition rates for both genuine and forgery signatures. The implemented system consists of a vector floating-point unit (VFPU), specifically designed for accelerating the floating-point computations involved in this biometric modality. Moreover, the proposed architecture also includes a microprocessor, which interacts with the VFPU, and executes by software the rest of the online signature verification process. The designed system is capable of finishing a complete verification in less than 68 ms with a clock rated at 40 MHz. Experimental results show that the number of clock cycles is accelerated by a factor of ×4.8 and ×11.1, when compared with systems based on ARM Cortex-A8 and when substituting the VFPU by the Floating-Point Unit provided by Xilinx, respectively.

Robotic Valet Parking System
Due to influx of vehicles on the road, citizens inevitably combat traffic congestion on a daily basis. This is underlined by the lack of parking infrastructure and shoot up of vehicle to human population ratio. The Robotic Valet Parking System uses the robotic valets, which are the vehicle carriers and parks the vehicles compactly in a given space of the parking area once the driver loads his vehicle at the loading bay. Robotic Valet Automated Parking System (APS) provides solution for the parking problems without the need for special construction for automation. The conventional concrete garages can be transformed into an automated parking system with the use of robotic valets. Since the robotic valet APS requires concrete flooring, which provides the fire separation, builders consider it approvable. The number and the position of the occupied vehicles can be determined without the deployment of the sensors in each of the parking slots. The vacancy of the parking garage is displayed on the LCD screen which is of benefit to the costumer. The central processing unit wirelessly controls the locomotion of robotic valets and the arrangement of vehicles in the parking area. We shall prove the space efficiency, accuracy, operational speed, safety and cost effectiveness of the proposed parking system. A functional prototype of a robotic valet is built which parks the vehicle loaded. The Unified Technology Learning Platform (UTLP) Kit, which has TI (Texas Instruments) ARM CORTEX A-8 microprocessor unit embedded in the TI OMAP 3530 applications processor, is the control unit and this monitors the movement of the robotic valet wirelessly. On producing the parking slip at the exit the robotic valet automatically retrieves the vehicle to the costumer.
Software-defined Radio based On Cortex-A9
This paper presents an implementation of Software-defined Radio (SDR) system over ARM Cortex-A9 processor. Compared with conventionally used general purpose CPU, e.g. X86 CPU, ARM processors have advantages in both price and power consumption under the same computing capability. Two basic issues of SDR over ARM are investigated: the real-time operation and signal processing efficiency. For the former issue, we select the Linux-based real-time operating system Xenomai, which is built on Cortex-A9 platform. Testing results show that the performance of Xenomai on Cortex-A9 meets the real-time requirement of SDR. Furthermore, the NEON technology of Cortex-A9 is used to optimize the complex signal processing algorithms in communication systems. Soft Demodulation is taken as an example for the optimization, and the experimental results are provided to show the improvement of signal processing efficiency.
