MVP 01 - page orientation

kolhizin commented 5 years ago

Create tool to identify orientation of text and probability of any text at all.

Get distribution of total absolute variance by angle from Radon R&D
Normalize on mean sum of image inside center square
Return all local maximas (apart at least specified distance in angles) with (angle, magnitude, width at 3 points: 25%, 50%, 75% distance to mean)

def get_text_angle(image, min_local_maxima_dst, interval_points)

Returns list of (angle, magnitude, list of widths).

python module with function, that returns index of probability of text and probable angles with width and index of probability
