How to create a motion blur effect?

How do you make an jpg file have the effect so that it looks like it's only moving from left to right or from top to bottom? I know it's something involving convolution and loops, but I have no idea how to do it.

Do you have any examples of what you're talking about?

A motion blur effect without depth information is basically just a direction blur and as you only want to blur in vertical/horizontal direction you can further simplify this to the vertical/horizontal pass of a two pass blur. Just google "two pass blur" and you should get plenty of information on how to achieve this.

@KevinWorkman, It's the same project that this person is posting http://forum.processing.org/two/discussion/3203/syntax-for-convolution#Item_3 We have to create a motion blur on a basketball and then put it over an image background later.

@mischi, I understand the general concept of it, but I don't know how to put it into code itself.

Please, don't create multiple threads for the same question. At least link to your second thread: http://forum.processing.org/two/discussion/3340
