This paper presents the use of local oriented energy features for real-time object tracking on embedded vision systems. Local oriented energy features are extracted using complex Gabor filters. Filtering is carried out across multiple channels with different frequencies and orientations. The effectiveness of the chosen feature set is tested using a mean-shift tracker. Our experiments show that adding...
Face detection has been widely used in many fields such as security, intelligent human interface etc., and concerns on how to meet the criterion of miniature and real-time have gradually become independent research topics. Traditionally, systems of face detection/recognition are either implemented in very specific hardware or software system. This paper tailors an algorithm of face detection using...
In this research, a fuzzy logic controller is designed for vision-based autonomous road-following. Because of its high-speed response, portability, and flexibility, a field programmable gate array is applied to implement this control system. Furthermore, a novel hardware/software partitioning method using the genetic algorithm is developed. This method is capable of finding the tradeoff among several...
Smart cameras are becoming more popular in human computer interaction (HCI). One of HCI research areas, multimodal user interface (MMUI) allows user to interact with a computer by using his or her natural communication modalities, such as speech, pen, touch, gestures, eye gaze, and facial expression. This paper presents the hardware and software co-design and implementation of KLT (Kanade Lucas Tomasi)...
The following topics are dealt with: advanced design space exploration techniques for multimedia systems; cost efficient and high performance computer vision systems; modeling and performance analysis of dynamic reconfigurable systems; code generation techniques; operating system and architecture for FPGA-based multimedia systems; software synthesis for multimedia applications; and dynamic QoS control...
Hardware/software partitioning of algorithms is gaining more and more importance in order to benefit from the advantages of both worlds. Pure software implementations are easy to change but the processing time is rather high. By contrast pure hardware implementations usually result in faster processing due to inherent parallelism but they do not offer the necessary flexibility for quick changes and...
This paper presents a synthesis tool for the automatic translation and optimization of bioinspired vision models into a FPL implementation. The software allows functional simulation and high level specification of the model, and produces a data-flow model using VHDL, which is synthesizable with different lower-level synthesis tools and for various FPGA technologies. The proposed design platform extends...
In this paper, we present a tool devised for the automatic design and optimization of bioinspired visual processing models using reconfigurable hardware. We have focused on the simulation and optimization characteristics of our system. We also present a retina-like processing system based on a PCI-based FPGA board as an example. The whole system is intended for the design and analysis of real-time...
Gabor method of multiscale image representation is very useful in many computer vision applications and to simulate the human being visual system. However, this transform is characterised by repetitive and iterative operations on large amounts of data, which imply a high computational cost. In this point is when the hardware/software codesign technique makes sense. In this work we have implemented...
