Frequently Asked Image Processing Algorithms Interview Questions

Q – 1 Explain procedure to implement highlight as a blinking
operation?

Ans- The function textattr in conio.h can be use for this
purpose a small program has presented here…

#include
int main()
{
textattr(129);
cprintf(“My name is Lord Blade…”);
return 0;
}

here in the textattr till 128 only colors would be set and
more than it colors with blink.

Q – 2 What are the different types of Structural Patterns?

Ans- One of the great features of modern programming languages is structural pattern matching on algebraic data types. Once you’ve used this feature, you don’t ever want to program without it. You will find this in languages like Haskell and Scala.

Q – 3 What is the algorithms of of Geographic information system project?

Ans- A geographic information system is a system designed to capture, store, manipulate, analyze, manage, and present all types of geographically referenced data.

The acronym GIS is sometimes used to mean geographical information science or geospatial information studies; these latter terms refer to the academic discipline or career of working with geographic information systems.[1] In the simplest terms, GIS is the merging of cartography, statistical analysis, and database technology.

Q – 4 Explain What is Rectification in image processing?

Ans- Image rectification is a transformation process used to project two-or-more images onto a common image plane. It corrects image distortion by transforming the image into a standard coordinate system.

It is used in computer stereo vision to simplify the problem of finding matching points between images.
It is used in geographic information systems to merge images taken from multiple perspectives into a common map coordinate system.
