Reconstruction of Signal using Interpolation

Reconstruction of Signal using Interpolation

Signal processing techniques are essential for accurately converting continuous signals to digital formats and vice versa. When a continuous signal is sampled with a period T, the resulting sampled signal exhibits replicas of the original spectrum in the frequency domain, spaced at intervals equal to the sampling frequency. To handle this sampled signal, a zero-order hold method can be applied, which creates a piecewise constant signal by retaining each sample's value until the next...

Relative Motion Analysis using Rotating Axes

Relative Motion Analysis using Rotating Axes

Consider a component AB undergoing a linear motion. Along with a linear motion, point B also rotates around point A. To comprehend this complex movement, position vectors for both points A and B are established using a stationary reference frame.
However, to express the relative position of point B relative to point A, an additional frame of reference, denoted as x'y', is necessary. This additional frame not only translates but also rotates relative to the fixed frame, making it...

Relative Motion Analysis using Rotating Axes-Problem Solving

Consider a crane whose telescopic boom rotates with an angular velocity of 0.04 rad/s and angular acceleration of 0.02 rad/s2. Along with the rotation, the boom also extends linearly with a uniform speed of 5 m/s. The extension of the boom is measured at point D, which is measured with respect to the fixed point C on the other end of the boom. For the given instant, the distance between points C and D is 60 meters.
Here, in order to determine the magnitude of velocity and acceleration for point...

Relative Motion Analysis - Velocity

Relative Motion Analysis - Velocity

A stroke engine has a slider-crank mechanism that converts rotational motion from the crank into linear motion of the slider or vice versa. This mechanism consists of three main parts: the crank, the connecting rod, and the slider.
When an external force is exerted, it sets the crank into a rotational movement. This, in turn, instigates the motion of the connecting rod, leading to what is referred to as a general plane motion. This process involves two key points - point A on the connecting rod...

Curvilinear Motion: Rectangular Components

Curvilinear Motion: Rectangular Components

Curvilinear motion characterizes the movement of a particle or object along a curved path, notably evident when envisioning a car navigating a winding road. If the car starts at point A, its position vector is established within a fixed frame of reference, where the ratio of the position vector to its magnitude signifies the unit vector pointing in the position vector's direction.
As the car advances, its position evolves over time. Quantifying the car's velocity involves computing the...

Absolute Motion Analysis- General Plane Motion

Absolute Motion Analysis- General Plane Motion

Visualize a drone, with its propellers spinning rapidly, hovering mid-air. The fascinating movements and operations of this drone can be comprehended by applying the principle of general plane motion.
As the drone's propellers rotate, an upward force is generated that counteracts the force of gravity, enabling the drone to lift off from the ground. This initial movement of the drone is along a straight path, representing a form of translational motion. In this phase, every point on the...

Background:

Distributed video coding (DVC) offers low-complexity encoding by leveraging decoder-side statistics.
Transform domain Wyner-Ziv (TDWZ) is an efficient DVC approach, but its performance relies heavily on side information and noise modeling.
Existing methods often struggle with accurate side information and noise residual estimation.

Purpose of the Study:

To enhance the efficiency of transform domain Wyner-Ziv (TDWZ) video coding.
To improve the quality of side information and noise residual frames in DVC.
To develop advanced motion and reconstruction re-estimation techniques for TDWZ codecs.

Main Methods:

Proposed a motion re-estimation technique using optical flow to refine side information and noise residual frames.
Introduced a noise residual motion re-estimation technique incorporating residual motion compensation and motion updating.
Developed a generalized reconstruction algorithm for optimizing multi-hypothesis reconstruction.
Integrated these techniques (MORE) into the SING TDWZ codec.

Main Results:

Achieved significant improvements in TDWZ coding efficiency for Wyner-Ziv frames (GOP size 2).
Demonstrated an average Bjøntegaard PSNR improvement of 2.5 dB compared to the DISCOVER codec.
Observed up to 6 dB PSNR improvement in specific scenarios.

Conclusions:

The proposed motion and reconstruction re-estimation (MORE) techniques effectively enhance TDWZ video coding.
The integration of MORE into the SING TDWZ codec leads to substantial coding gains.
The developed methods offer a notable advancement in DVC performance, particularly in managing side information and noise.
