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 instrumental in...

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...

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 drone...

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...

Relative Motion Analysis using Rotating Axes - Acceleration

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. The absolute velocity of point B is determined by adding the absolute velocity of point A, the relative velocity of point B in the rotating frame, and the effects caused by the angular velocity within the rotating frame.
Time differentiation is...

Relative Motion Analysis - Acceleration

A slider-crank mechanism 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. The movement of the slider-crank is an example of general plane motion as the fluctuating angle between the crank and the connecting rod. Consider a segment AB where point A is at the end of the slider and point B is on the diametrically opposite end to point A, on a crack. The variance in...

Background:

Object tracking in videos is crucial for various applications.
The mean shift (MS) algorithm, using the Bhattacharyya coefficient, is a prominent method for object localization.
Standard MS algorithm performance degrades due to background clutter, illumination variations, and occlusions.

Purpose of the Study:

To enhance the robustness and accuracy of the mean shift algorithm for object tracking.
To overcome limitations of the MS algorithm, including partial and full occlusions, low saturation, and sudden lighting changes.
To improve real-time object tracking capabilities.

Main Methods:

Proposed an improved convex kernel function to handle partial occlusions.
Integrated motion information with color features to enhance performance under low saturation and varying illumination.
Utilized a Kalman filter, assuming constant object speed, to address full occlusion scenarios.

Main Results:

The integrated approach, combining color and motion information, significantly increases the MS algorithm's capability.
Experimental results demonstrate optimal performance in real-time object tracking.
The proposed enhancements lead to more reliable tracking compared to the original MS algorithm.

Conclusions:

The improved MS algorithm offers a robust solution for real-time object tracking in challenging video conditions.
Simultaneous use of color and motion features, along with Kalman filtering for occlusions, enhances tracking accuracy and reliability.
