Window

BaseWindow

class logio.dynamic_time_warping.BaseWindow[source]

Base class on which the desired window constraint is built upon. The warping window intuitively controls the amount of distortion allowed when comparing a pair of well logs.

Generally they are two types of wapring windows: 1. Sakoechiba’s Window implemented in SakoechibaWindow class. 2. Itakura’s Window implemented in ItakuraWindow class.

Length of query log.

Type: int

len_y

Length of reference log.

Type: int

_gen_window(len_x, len_y):: Generates the window constraint matrix.
