About the course:-
The availability of huge volume of Image and Video data over the internet has made the problem of data analysis and interpretation a really challenging task. Deep Learning has proved itself to be a possible solution to such Computer Vision tasks. Not only in Computer Vision, Deep Learning techniques are also widely applied in Natural Language Processing tasks.

then which one of the following will be true?
Answer :-
4. Suppose Fourier descriptor of a shape has K coefficient, and we remove last few coefficients
and use only firstm (m<K) number of coefficients to reconstruct the shape. What will be effect
of using truncated Fourier descriptor on the reconstructed shape?

Answer :-
8. Given an image | (fig 1), The gray co-occurrence matrix C (fig 2) can be constructed by specifying the displacement vector d = (dx, dy). Let the position operator be specified as (1, 1), which has the interpretation: one pixel to the right and one pixel below. (Both the image and the partial gray co-occurrence is given in the figure 1, and 2 respectively. Blank values and ‘X’,’Y’ values in gray co-occurrence matrix are unknown.)
