How do I start ios shape animations at different times based on the position of another shape that is already moving
by PeterYunZhang in Programming Languages

I'm trying to do the following animation for my iPhone App. My current thoughts are to inherit from CAShapeLayer and build up a shape that has the 3 components for the animation. I.e. the yellow rectangle, the green line and the red pointer. I have a basic animation working where I animate the yellow box, but now I'm wondering how to do I start the red pointer's animation at the right time.

OpenCV - detecting a shape in a shape collection (e.g. human in a group of humans)
by Bong Munoz in Development Tools & Services

I am performing blob extraction from video and using the blob's aspect ratio to classify into humans or vehicles. Works pretty well since vehicles and humans have quite differentiated aspect ratios.

However this logic breaks down when a group of humans - say mother & child holding hands, or a group walking closely, come by and the blob detection is one single blob.

Distinguish between leaving shape and entering overlapping shape (KineticJS)
by mhedberg in Web Design

Drawing a shape but keeping the most previous shape on screen in java
by Murali Ravipudi in Java

I've created a function to where I can click somewhere in a Jpanel and it draws a shape at the position where the mouse clicked. The problem I am having is when I click in a new position, it moves the shape and redraws it. I would like the previous shape to "Burn" into the screen and stay there. It doesn't have to have any data tied to it, I just want the image of the shape to show where it use

How to Shape a Japanese Blueberry Shrub Into a Tree Shape
by fukas78 in Home & Garden
The Japanese blueberry shrub is an attractive evergreen. Its green, glossy leaves turn bright red in the autumn and will drop off, but new leaves will immediately grow in; new leaves are usually bronze-colored. Japanese blueberry shrubs display creamy-white, bell-shaped flowers in the spring, and landscapers praise its blue-black berries for not staining sidewalks. Different varieties of Japanese
