algorithm to find if closed path is rotating in right or left direction(finding right hande rule direction of closed loop)

A very simple mathmatical method exist to solve this problem. https://mathworld.wolfram.com/PolygonArea.html here is an interactive example: https://demonstrations.wolfram.com/SignedAreaOfAPolygon by calculating the signed area of a polygon, one can easily determine if a 2D directed path is rotating in the right or left direction.

FCN, UNet, FPN comparison

The three all seem to have “downsampling and then upsampling” idea at the core. But what are the differences? Which one is the correct one to coin when referencing the “downsampling + upsampling” idea? Fully Convolutional Network(FCN) submitted: 2014.11.14https://arxiv.org/pdf/1411.4038.pdf remove any dense(fully connected) layers and only use convolution layers. downsampling Read more…
