"3. Load an interesting image, and then blur it with cv::smooth() using a Gaussian
filter.
a. Set param1=param2=9. Try several settings of param3 (e.g., 1, 4, and 6). Display
the results.
b. Set param1=param2=0 before setting param3 to 1, 4, and 6. Display the results.
Are they different? Why?
c. Use param1=param2=0 again, but this time set param3=1 and param4=9.
Smooth the picture and display the results.
d. Repeat Exercise 3c but with param3=9 and param4=1. Display the results.
e. Now smooth the image once with the settings of Exercise 3c and once with
the settings of Exercise 3d. Display the results.
f. Compare the results in Exercise 3e with smoothings that use
param3=param4=9 and param3=param4=0 (i.e., a 9 × 9 filter). Are the results the
same? Why or why not?"
as i kown,cv::smooth() is out of use for quite a long time (am i right,i cant find it neither in the code nor in the book) ,then how to solve this problem,and where is the param1?param2?
You are right, the smoothing functions are now:
cv::blur
cv::GaussianBlur
cv::medianBlur
cv::bilateralFilter
I am forwarding this to OReilly errata for Learning OpenCV 3
OK,have done
