Basic Filtering in the Frequency Domain
1 Low-pass
Take the Discrete Fourier Transform (DFT) of an image (use the fft2 command in Matlab) and multiply its spectrum by a circle of a diameter that retains about ¼ of the lowest spatial frequencies. Note: make sure the DC part of the DFT and filter are centered. The center of the circle should have a value of 1 and the remainder 0. Take the inverse DFT of the product and visually verify that the results looks like a low-pass filtered image. This is one version of a low-pass filter.
Compare this low-pass filter’s frequency response to that of the uniform filter in Chap. 3 and note the difference. The circle is in the filter used above is its frequency response. For the uniform filter, put a 3 x 3 array of 1/9 in a matrix, then pad that matrix with zeros until it is the same size as your circle image. Then take it’s DFT and plot it’s absolute value to see its frequency response.
2 High-pass
Filter an image like you did above, but with a circle of that retains about ½ the highest spatial frequencies. In this case, the center of the circle should be 0, and remainder 1.
Compare this filter’s frequency response to the Sobel edge operators. Meaning, add the absolute values of the frequency responses for gx and gy of the Sobel operators. Describe the differences between the two filters, Sobel and circle.

Dear Sir or Madam,
I am seeking professional assistance in writing a scientific article focused on the phenomenon of cybersickness in virtual reality (VR) environments. The article should adhere to a strict 6-page limit, including references, and is intended for submission to an upcoming conference. Below, I outline the desired structure and specific elements to be included in the manuscriipt.
Objective:
The paper aims to explore cybersickness and its under-researched contributing factors such as stress, cognitive load, and movement (body and head movements). This investigation is motivated by observations from our VR training programs for law enforcement, which suggest higher instances of cybersickness than previously reported in literature.
Structure and Content:
My abstract (keep exactly this one):
This survey focuses on a crucial issue in virtual reality (VR) – cybersickness. Cybersickness is similar to motion sickness, but occurs with electronic screens or VR displays, as opposed to actual movement. Cybersickness refers to a cluster of symptoms, including nausea, eye strain, vertigo and sweating, to name a few. Some studies have reported that roughly 40% of the population may suffer from cybersickness. In our projects, we are interested in using VR for training of law enforcement officers, thus the scenarios are often stressful, involve several head movements (e.g., during surveillance) and often fast-moving scenes (e.g., car chases). We have observed over the years that our cybersickness statistics are usually higher than those reported in the literature. In this survey, we explore the literature to see if there have been any reported links between stress, cognitive load, and head and body movement to cybersickness levels. A total of xx papers were surveyed. Findings were often mixed and inconclusive, but pointed towards a positive relationship between cybersickness and both cognitive load and stress. Studies looking at head movements, on the other hand, showed a negative relationship with levels of cybersickness. It is hoped that these insights may help VR researchers develop new training protocols that can be more comfortable for users.
Introduction (1 page):
Introduce the concept of cybersickness, defining it and distinguishing it from traditional motion sickness. (Don’t forget to put references when you state something.)
Talk about factors hindering cybersickness (see PDF in attachment for example)
Highlight the relevance of studying stress, cognitive load, and physical movements (head and body) as potential contributors to cybersickness, emphasizing the novelty and necessity of this investigation (in line with our futur project with law enforcement).
Literature Review (Sections 2-4, approx. 3 pages):
Each section should focus on one of the three factors (stress, cognitive load, movements) and review existing literature, incorporating findings from the provided Excel file of scientific articles. you will also have to find new ones. Specifically:
Section 2: Impact of Stress on Cybersickness
Section 3: Impact of Cognitive Load on Cybersickness
Section 4: Impact of Movements on Cybersickness
Moreover, include analyses from the following papers, ensuring they are integrated into the respective sections:
Link to paper on Frontiers : https://www.frontiersin.org/articles/10.3389/frvir.2022.943409/full
Link to paper on IEEE Xplore : https://ieeexplore.ieee.org/abstract/document/9419213
Please ensure the article focuses on how the identified factors, such as stress, cognitive load, and physical movements, impact the onset of cybersickness, rather than the reverse scenario where, for example, cybersickness induces responses like stress in individuals. Additionally, it would be beneficial to include a table in each section summarizing the key findings, similar to the format utilized in the provided Excel file, to clearly present the data and analyses.
Discussion (1 page):
Discuss the implications of the literature findings in the context of VR training for law enforcement, including stress-inducing scenarios, surveillance activities, and dynamic scenes like car chases. Propose recommendations for future VR training protocols that could mitigate cybersickness, based on our project’s objectives and observations.
Conclusion (0.5 pages):
Summarize the key insights and their potential impact on developing more effective and comfortable VR training programs for law enforcement officers.
References (0.5 pages):
List all cited works, ensuring adherence to the conference’s formatting guidelines.

Read the following:
Reliability Engineering/ERAU Hunt Library – O’Reilly
Chapter 2 (Sections 2.2), Hazard Rate
An idealized (though rarely occurring) shape of the hazard rate of a product is the bathtub curve. The bathtub curve is a model for system reliability, including early life burn-in and eventual wear-out at the system’s end of life.
The ‘bathtub’ refers to the shape of a line that curves up at both ends, similar in shape to a bathtub. The bathtub curve has 3 regions:
The first region has a decreasing failure rate due to early failures.
The middle region is a constant failure rate due to random failures.
The last region is an increasing failure rate due to wear-out failures.
Considering the above diagrams and considering the piecewise linear bathtub hazard function defined over the three regions of interest given below. The constants in the expressions are determined to satisfy the normal requirements for h(t) to be a hazard function.
Address the following questions in this discussion:
Briefly describe each region of the bathtub curve.
Develop the equations for the reliability function and the probability density function for the time to failure random variable based on the above hazard function.
How does the bathtub curve concept, which encompasses phases of early failures, random failures, and wear-out failures, relate to and impact the reliability of a system? Additionally, demonstrate your understanding by applying statistical techniques to model system reliability based on the given hazard function.
