1. Do You Know What Rectification Is In Image Processing?

Answer: They are as follows.

– Rectification in Image Processing 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.

2. What Is Meant By Illumination And Reflectance?

Answer: Illumination is the amount of source light incident on the scene. It is represented as i(x, y). Whereas, Reflectance is the amount of light reflected by the object on the scene. It is represented by r(x, y).

3. List The Categories Of Digital Storage?

Answer: They are as follows.

– Short term storage for use during processing.

– Online storage for relatively fast recall.

– Archival storage for infrequent access.

4. What Are The Differences Between Structural Patterns & Morphological Structural Element?

Answer: In software engineering, structural design patterns are design patterns that ease the design by identifying a simple way to realize relationships between entities.

5. Write Short Notes On Neighbours Of A Pixel?

Answer: They are follows.

– The pixel p at co-ordinates (x, y) has 4 neighbors (ie) 2 horizontal and 2 vertical neighbors whose co-ordinates is given by (x+1, y), (x-1,y), (x,y-1), (x, y+1). This is called as direct neighbors. It is denoted by N4(P)

– Four diagonal neighbors of p have co-ordinates (x+1, y+1), (x+1,y-1), (x-1, y-1),(x-1, y+1). It is denoted by ND(4).

– Is a combination of 4 direct neighbors and 4 diagonal neighbors. Eight neighbors of p denoted by N8(P)
