readFrame: Read Specific Video Frame

Description

Usage

readFrame(x, pos, target = "new")

Arguments

x

A Video object.

pos

An integer corresponding to the position of the frame to read in the video.

target

The location where the results should be stored. It can take 2 values:

• "new":a new Image object is created and the results are stored inside (the default).

• An Image object:the results are stored in another existing Image object. This will replace the content of target. Note that target must have the same dimensions as x.
