why does have to short-circuit secondary wire of current transformer ?

The full wave rectifier is a means of converting alternating current (ac) into direct current (dc). It is done with either the use of 2 diodes coming off a center tapped transformer, or by using a bridge rectifier, which conists of 4 diodes ganged together in a certain configuration. As it's name implies, it converts both the positive going and the negative going parts of the sign wave into useable dc, and therefore is more efficient than a half wave rectifier, which only converts 1/2 of the complete sign wave into useable dc.

please tell me ... which recent topics are going in digital image processing for research area .

If the orientation of the letter "e" on the slide is exactly the same as it appears in this response, then the image of the "e" would be an inverted reflection.

In lamens terms, the "e" would be upside down inside the microscope.

When you convert digital signal to analog, it is called as an analog signal.

The device used is called digital to analog converter.

The fundamental components of digital image processing are computer-based algorithms. Digital image processing allows a much wider range of algorithms to be applied to the input data and can avoid problems such as the build-up of noise and signal distortion during processing.

Image processing is the method of processing data in the form of an image. Image processing is not just the processing of image but also the processing of any data as an image. It provides security.

Binary images, Indexed images, Grayscale images, True color images

In this process, a 2D image on a screen or paper is "rendered" or turned into a 3D image by the use of computer programs. It also produces effects to produce the final video output.

image segmentation refers to clustering or grouping of homogeneous pixels into various groups while classification is next hierarchy which labell those clustered pixels as different classes..
