Manipulating Images Using Arithmetic

in this lab i will be learning how to manipulate  images using arithmetic in the GIMP program

loading the file into GIMP

the picture below shows artistic filter which makes the picture look more like a painting that enfasizes certain parts of the picture. there are many other filters you can use such as blur, distort and enhance.

the pictures below show 2 different convolution matrix and the changes that they will do to the original picture

3x3 of 's

although the picture is simular to the original this filter slitely distorts image and colour.

3x3 with 1's and -1's

this picture is alot more blurry than the original pucture it  looks like it has been taken with moving camera or a unfocused lense.

at the end of this lab i have learned the basics of  manipulating  images using arithmetic in GIMP. by using the filter in GIMP next week will be on video prossesing.
