Hi all,
I updated my version of the image region vocabulary/doc.
width and height for regions have been removed, the value
syntax for boundingBox is now {x1,y1,width,height}.
Is the following coords stuff correct:
[[
A region of type Rectangle uses two pairs of comma-separated integers. the
pairs are separated by a space. "0,0 50,100" could for example describe a
rectangle that starts in the upper left corner of an image, has a width of 50
pixels and a height of 100 pixels (i.e. the first pair describes the upper left
corner, the second one the lower right).
A region of type Circle uses a point (center) and a radius. "40,60,20" is a
valid example (center_x=40, center_y=60, radius=20).
A Polygon can be described by a list of pairs. Each pair consists of two
(comma-separated) integers. Pairs are separated by a space. "0,0 50,0 50,100
0,100" describes the rectangle mentioned above as a polygon.
The coords value for an Ellipse consists of four comma-separated values. In
this context "40,60,20,15" means: center_x=40, center_y=60, x_radius=20,
y_radius=15.
]]
