Various methods do exist for facial expression recognition and it's still a challenging task to get accurate results on unseen images due to lack of generalizability. To improve generalization Local Binary Pattern (LBP) are used as feature extraction. Facial parts like eyes, nose and mouth are detected and template is created for each image in dataset. The template of reference image is matched with...
Yield and loss prediction plays an important role in the planning and operation of solar PV systems. The performance of a solar PV system depends on the location, system design, field of view, and the orientation of the solar panels in a given system. Some design and simulation tools are designed by professionals to connect to efficient planning and grid operations as well as stand-alone solar photovoltaic...
This paper demonstrates a nonlinear robust controller design for the twin rotor control system (TRCS). TRCS is a multiple-input-multiple-output (MIMO) system having nonlinear, unstable and coupled dynamics. The proposed controller is designed using dynamic surface control (DSC) technique. The DSC is advance version of integral Backstepping control approach through the use of dynamic low pass filters...
The common marmoset is emerging as an important transgenic model for improving the understanding of the underlying neurological basis of many brain disorders. Automated systems for quantitative monitoring of marmoset behaviors in naturalist settings over long period of time are needed to facilitate this process. This paper presents the preliminary work toward building a novel multimodal acquisition...
Facial expression carries information about the emotional and physical state of a human being. In the past few years facial expression recognition has become a promising research area. With the developing robotic era the systems needs intelligence to understand human's behavior. Expression recognition is applied and useful from emoticons to disease detection in medical field. Apart from automated...
This paper presents quantitative feedback theory (QFT) based control, input disturbance rejection and tracking of a twin rotor system. Twin rotor system is a class of multiple-input multiple-output (MIMO) system having complex nonlinearity. QFT is a robust frequency domain technique based on Nichols chart. This technique achieves desired robust design over a specified range of plant uncertainty. QFT...
This paper presents quantitative feedback theory (QFT) based control and tracking of ball and beam system. QFT is a frequency domain approach using Nichols chart. This technique achieves desired robust design over a specified range of plant uncertainty. QFT is used for the design of robust controllers for the plant with uncertainties in the parameters, input/output disturbances and noises. Ball and...
A number of vehicles may be controlled and supervised by traffic security and its management. The License Plate Recognition is broadly employed in traffic management to recognize a vehicle whose owner has despoiled traffic laws or to find stolen vehicles. Vehicle License Plate Detection and Recognition is a key technique in most of the traffic related applications such as searching of stolen vehicles,...
Space Applications Center (SAC) of Indian Space Research Organization (ISRO) designs and develops electro optical sensors for earth observations and inter-planetary exploration missions. The sensors are fairly complex systems involving linear/area imaging elements, optics, electronics having large number of spectral bands, making their development a highly challenging task. To ensure in-orbit performance,...
