  The face recognition is an application which is used for identifying or verifying a person from a digital image. The common problem that often occurs while identifying the face from image is due to the low resolution in images especially when it is captured from a long distance. In automated face recognition system, this has always been a challeging problem. To overcome this problem, an approach to learn relationship between the high resolution space and the VLR image space for face is proposed. In this new approach the face recognition applications under the VLR problem is designed for good visuality. To create the Very Low Resolution (VLR) image corresponding to each of these High Resolution (HR) images, the HR images are resized to 64x48 pixels. The Very Low Resolution (VLR) of the face image is <16x12 pixels. The proposed system is implemented in MATLAB. The performance of the proposed system is tested. The proposed system is highly accurate and extremely fast in processing the image data. Experimental results show that proposed method outperforms existing methods. The VLR face recognition problem has been defined and discussed in this study. For good visual quality applications, a new data constraint that measures the error in the HR image space was developed and RLSR was proposed.

  The general configuration of induction motor is generating a high initial current and high torque while it is undergone heavy load operation. The torque and current problems is depends on mechanical internal and external structure and control arrangement. In order to control of initial torque and motor performance via. current control an adequate circuit and control schemes are required to obtain desired motor performance. This study is proposes switched inductor based quasi Z source circuit is applied on dual source simplified H-bridge multilevel inverter for high step up PV power generation and controlled torque as well as stator current. Voltage control scheme is introduces to control of H-bridge circuit using reference voltage generation for 3 phase proposed circuit. The present circuit is used to control of over voltage and over current in proposed topology. This control loops is not required any complex control, here, we control and generate reference signals using direct sensing of DC-link voltage circuit. Dual power supply based switched inductor quasi Z source on simplified H-bridge multilevel inverter is controlled by single carrier multi-reference Phase Opposition and Disposition (POD) pulse width modulation. The 0.5 Hp induction motor is undergone for this circuit to verify about soft start and torque-current control using MATLAB/Simulink Software.
