- Start with horizons at 30% from top, then 40% and then 50%
- For each horizon, use box sizes from 0.25, 0.5, 1.0, 1.5 and 2.0 times trained BB sizes
- Scan left to right with 0.2 of above box width
- Catching kids: Kids will be a smaller box but on higher horizon. So a kid on 305 hoprizon will hopefully be identified by the smaller box at 50% horizon

08-Dec-2018: What does HoG do?
- Can we take a simple 2D figure like a house shape and plot HoGs to see what it looks like?
- How does it look for a rect.? A triangle? and then the house? A circle?
- A steep line vs a gently sloped line
08-Dec-2018: Understanding what gradients mean for images
- (Klette, 2014: 11): See 'Detecting Step-Edges by First- or Second-Order Derivatives'
- 1st order and 2nd order derivatives provide edge detection
- The 'curve' on which to do derivatives are intensities? Along X or Y axes
- Check using simple high contrast images developed in MS Paint
- See if we can plot the intensities along sections of a square and triangle and see expected itensity peaks
