• Why closed contours are guaranteed here?

  - by user198729

  Quoted from here: BW = edge(I,'zerocross',thresh,h) specifies the zero-cross method, using the filter h. thresh is the sensitivity threshold; if the argument is empty ([]), edge chooses the sensitivity threshold automatically. If you specify a threshold of 0, the output image has closed contours, because it includes all the zero crossings in the input image. I don't understand it,can someone elaborate?

• Why does string::find return size_type and not an iterator?

  - by dehmann

  In C++, why does string::find return size_type and not an iterator? It would make sense because functions like string::replace or string::insert take iterators as input, so you could find some character and immediately pass the returned iterator to replace, etc. Also, std::find returns an iterator -- why is std::string::find different?

• jQuery responds to click() differently for user and programmatic triggers

  - by Moss

  Here's the code: this.Form.find("input[type=checkbox]").click(function(event) { if ($(this).is(":checked")) { console.log("checked"); } else { console.log("unchecked"); } }); If the checkbox is not checked, and I click with the mouse, I get "checked". If I trigger it programmatically like $("#someCheckbox").click(), I get "unchecked". How to make the two behave the same way?

• What happens if I give more inputs in estimateRigidTransform or getAffineTransform?

  - by user3531608

  I am using estimateRigidTransform with about two vectors of 100 points and is working FINE. But somehow getAffineTransform doesn't work. I know that findHomography finds the best matrix using RANSAC and getPerspectiveTransform needs only 4 points. My question is what happens if I give more inputs in estimateRigidTransform or getAffineTransform? Does it take only 4 points from input matrix? Or do some kind of RANSAC?

  In many prototype scripting cases, it's easier to just stick every form item (such as an input or textarea) in its own form tag. Is there anything wrong that could happen from having lots (like 1000) form tags in a page?
