Algorithm to detect intersection of two rectangles?
...e = v(n) - v(n-1)
You can get a perpendicular to this by rotating it by 90°. In 2D this is easy as:
rotated.x = -unrotated.y
rotated.y = unrotated.x
So no trigonometry or slopes involved. Normalizing the vector to unit-length is not required either.
If you want to test if a point is on o...

Java(TM) SE Runtime Environment (build 1.8.0_91-b14)
Java HotSpot(TM) 64-Bit Server VM (build 25.91-b14, mixed mode)
Check what compiler is used

...ss of the number.
For example: -2 represented in 8 bits would be 11111110 (because the most significant bit has negative weight). Shifting it right one bit using arithmetic shift would give you 11111111, or -1. Logical right shift, however, does not care that the value could possibly represent ...
How can I quantify difference between two images?
... img2 = to_grayscale(imread(file2).astype(float))
# compare
n_m, n_0 = compare_images(img1, img2)
print "Manhattan norm:", n_m, "/ per pixel:", n_m/img1.size
print "Zero norm:", n_0, "/ per pixel:", n_0*1.0/img1.size
How to compare. img1 and img2 are 2D SciPy arrays here:
