Do anyone know whether one should expect questions from DIP or Software Engineering in upcoming ISRO exams for CS ? Both are not there in the current gate syllabus...

Answer 1

This question is related to Digital image Processing not Computer science 

 Pixel mask is formed by digits 1 and 0 to determine the positions to create a plot within the line path. For example, the mask 1111000 is used to show a dashed line with a dash length of 4 and inter point spacing of 3.

I agree Sir but in some Northern Engineering Colleges DIP is included in CSE & thus its in ISRO exam.

Thank you sir for the perfect answer :) :)
