Q3. Correct Syntax to read image in MATLAB in the current
folder
- var_image
= imread(‘my_image.jpg’)
- var_image
= imread(‘my_image’)
Q4. Select the correct option to crop the top-left 50×50
section from the image read below.
var_image = imread(‘my_image.jpg’)
- cropped_section
= var_image(0:50,0:50)
- cropped_section
= var_image(1:50,1:50)
- cropped_section
= var_image[0:50,0:50]
- cropped_section
= var_image[1:50,1:50]
Q5. What is initial data type of the image you read through
imread function of MATLAB?
- int8
- double
- uint8
Q6. I1 = imread(‘my_image.jpg’)
I2 = im2double(I1)
- Scales
the image intensity values from 0 to 1
- Converts
the image from uint8 to double format
- The
array dimensions remain same
Q7. Select the options which assign the height and width of
an image correctly in MATLAB.
var_image = imread(‘my_image.jpg’)
- [height,width]
= size(var_image ); (Ans)
- [width,height]
= size(var_image );
- image_dimension
= size(var_image );
width = image_dimension(1)
height = image_dimension(2)
- image_dimension
= size(var_image ); (Ans)
height = image_dimension(1)
width = image_dimension(2)
