In today's world, Artificial Intelligence (AI) has begun to take center stage. The recent trend has been moving towards the creation of robotic devices which are capable of making spontaneous and effective decisions in demanding situations. One of the challenges faced in such a scenario is dealing with the permutations and combinations of countless real-life circumstances, most of which require to comprehensively train the machine so that it is capable of taking appropriate actions, all the while taking care of any exceptions. Human errors may cause disastrous effects in certain circumstances; such errors can be reduced using AI. One of the most important uses of AI in recent times has been its application in automated vehicles. If the movement of vehicles were to be automated, much time can be saved, and moreover, some amount of travel related stress for humans is lifted. In order to implement the automation of locomotives, detection of any obstructions in the vehicle's path is a must. Also, the algorithm should be robust enough to detect any type of obstacle irrespective of it being a vehicle, barrier or people crossing the road. A successful attempt to perform the same has been discussed in this paper, through a novel yet simple algorithm utilizing image processing techniques. The simulation of the algorithm was performed using the Simulink tool in MATLAB, version 2012a. A success rate of 93% was achieved with respect to the detection of obstacles. © 2013 IEEE. Source

The concept of hand gesture recognition has been widely used in communication, artificial intelligence and robotics. It is a staple method of interaction especially for the deaf and the blind. Techniques for recognizing hand gestures are in great demand. Many algorithms have been discovered for this purpose, each of them having their own advantages and disadvantages. In this paper we present a novel algorithm for hand recognition using image processing and explore its application in security based systems. The algorithm was tested for different gestures on over 50 samples and an accuracy of 95.2% was achieved. In terms of speed, the algorithm is 1.5 times faster than its contemporaries. An alternative to finding the centroid based on a less computationally complex algorithm has also been explored. The algorithm was implemented in MATLAB programming language on MATLAB 7.13 build R2011b and SIMULINK. © 2013 Springer-Verlag Berlin Heidelberg. Source

Sign language is the most important methodology using which hearing and speech impaired people can interact with the rest of the world. Conversation with hearing impaired individuals gets complicated if the listener is ignorant of sign language. Hence it becomes important to construct a bridge between these two banks. Many sign language and hand gesture recognition algorithms have been developed in the recent years, to assist people who do not have knowledge of sign language to converse with the speech impaired but very few with good results exist. One of the major concerns with respect to hand gesture recognition is segregation or segmentation of the hand and identifying the gesture. This paper explores the various possible ways of segmentation using different color spaces and models and presents the best algorithm with highest accuracy to perform the same. Various experiments were conducted for over 500 different gestures and an accuracy of around 97.4% was achieved with the segmentation algorithm selected. The algorithms were implemented in MATLAB programming language on MATLAB 7.14.0.739 build R2012a. © 2013 IEEE. Source

Almost undoubtedly, the greatest invention of the 20th century has been the computer. The computer uses several auxiliary devices to establish a seamless interaction with the user. One challenge faced during the development of these devices, was the lack of direct interfacing between the machine and the user. Today we see Natural User Interfaces (NUI), which include touch activated and speech activated inputs. One problem faced with the touch NUI's is ambiguity. This is mainly due to variations in finger size, proximity of icons, and the fact that the imprint of the finger, called a fingertip blob, may have to be mapped to a single pixel. In this paper we attempt to address the above problems, by focusing on achieving a high level of accuracy at low costs, utilizing image processing techniques, all the while keeping the process simple and fast. A novel algorithm for the same has also been discussed. The algorithm was implemented using the Java programming language on the Java Software Development Kit (JDK) version 1.5.0 (update 22). An accuracy of 100% in fingertip blob detection was achieved and an improvement of 15% was achieved in terms of execution time in comparison with existing algorithms, for various experiments conducted utilizing the new algorithm. © 2012 IEEE.

With the advent of new technology in the fields of VLSI and communication, there is also an ever growing demand for high speed processing and low area design. It is also a well known fact that the multiplier unit forms an integral part of processor design. Due to this regard, high speed multiplier architectures become the need of the day. In this paper, we introduce a novel architecture to perform high speed multiplication using ancient Vedic maths techniques. A new high speed approach utilizing 4:2 compressors and novel 7:2 compressors for addition has also been incorporated in the same and has been explored. Upon comparison, the compressor based multiplier introduced in this paper, is almost two times faster than the popular methods of multiplication. With regards to area, a 1% reduction is seen. The design and experiments were carried out on a Xilinx Spartan 3e series of FPGA and the timing and area of the design, on the same have been calculated. © 2013 IEEE. Source
