A handy list of VideoCapture object parameters taken from official OpenCV docs.
CAP_PROP_POS_MSEC =0, //!< Current position of the video file in milliseconds.
CAP_PROP_POS_FRAMES =1, //!< 0-based index of the frame to be decoded/captured next.
CAP_PROP_POS_AVI_RATIO =2, //!< Relative position of the video file: 0=start of the film, 1=end of the film.
CAP_PROP_FRAME_WIDTH =3, //!< Width of the frames in the video stream.
CAP_PROP_FRAME_HEIGHT =4, //!< Height of the frames in the video stream.
CAP_PROP_FPS =5, //!< Frame rate.
CAP_PROP_FOURCC =6, //!< 4-character code of codec. see VideoWriter::fourcc .
CAP_PROP_FRAME_COUNT =7, //!< Number of frames in the video file.
CAP_PROP_FORMAT =8, //!< Format of the %Mat objects returned by VideoCapture::retrieve().
CAP_PROP_MODE =9, //!< Backend-specific value indicating the current capture mode.

Simple example of gradient descent in tensorflow
import tensorflow as tf
x = tf.Variable(2, name='x', dtype=tf.float32)
log_x = tf.log(x)
log_x_squared = tf.square(log_x)
optimizer = tf.train.GradientDescentOptimizer(0.5)
train = optimizer.minimize(log_x_squared)
init = tf.initialize_all_variables()

Background Averaging (Background Subtraction) in Python+OpenCV
import numpy as np
import cv2
class BackGroundSubtractor:
# When constructing background subtractor, we
# take in two arguments:
# 1) alpha: The background learning factor, its value should
# be between 0 and 1. The higher the value, the more quickly
# your program learns the changes in the background. Therefore,
