일상생활에서 보여지는 장면은 광원에 의하여 반사된 물체들이 우리의 시신경에 의하여 인식되어 나타나지는 것이다. 우리 눈에 보이는 빛을 광선으로 가정할 때 이를 모방하여 특정 조명에서 나오는 색상, 광도, 방향을 컴퓨터에서 모델링하는 것은 정확하고 사실적인 렌더링의 가장 기본적인 부분이다. 컴퓨터 그래픽스 분야에서 장면(scene)에 비춰지는 조명은 주변광(ambient), 난반사광(diffuse), 정반사광(specular)의 결합으로 주로 표현하며 오브젝트 표면에서의 빛의 반사를 나타낸다[1]. 실세계에서는 표면에서의 빛의 반사 외에 다른 물체에 의해 반사되거나 투과, 굴절되어 들어오는 빛과 같은 여러 가지 간접조명이 존재하는데 3차원 모델링에 이러한 간접조명을 적용할 경우 더욱 사실적인 표현이 가능하다. 그러나 오브젝트 간에 주고 받는 빛의 영향을 모두 고려하기 때문에 렌더링 시간이 길어지고, 또한 표면내부 산란효과와 같은 간접 조명 효과를 표현하기 어렵다.
...
본 논문에서는 직접광과 간접광 성분의 정확한 분리를 위해서 이러한 장면에 대한 밝기의 오차를 줄이는 방법을 제시한다. 고주파 조명을 사용할 경우 거울 구면과 같이 정반사가 심한 물체에서는 분리 결과가 제대로 나오지 않는다. 이런 한계점을 고려하여 조명 패턴의 픽셀 크기 별로 조명과 물체의 거리에 따른 직접광과 간접광의 분리 실험을 통하여 적절한 조명의 위치를 찾았다. 그리고 물체의 속성에 따른 빛이 비춰지지 않은 영역에 존재하는 빛의 값을 설정하는 방법을 보여준다. 이러한 실험을 통하여 물체의 재질과 속성에 맞는 값을 설정함으로 직접광과 간접광 성분을 분리결과의 정밀도를 높일 수 있다.
그리고 장면의 분리 방법을 응용하여, 포장으로 쓰이는 내부가 보이지 않는 반 투명한 비닐커버에 가려진 물체 형태를 간접광 성분으로 하였으며, 여기에 이미지 향상 기법을 적용하여 커버내부의 물체를 좀더 정확하게 보여지게 하였다.
이와 같은 연구는 컴퓨터 비전, 이미지 처리, 웹 카메라의 성능개선과 BRDF함수의 성능개선 등 다양한 분야에서 활발하게 활용될 수 있을 것으로 예상된다

Product Design Trends in 2024 | Teenage EngineeringsPixeldarts
The realm of product design is a constantly changing environment where technology and style intersect. Every year introduces fresh challenges and exciting trends that mold the future of this captivating art form. In this piece, we delve into the significant trends set to influence the look and functionality of product design in the year 2024.
How Race, Age and Gender Shape Attitudes Towards Mental HealthThinkNow
Mental health has been in the news quite a bit lately. Dozens of U.S. states are currently suing Meta for contributing to the youth mental health crisis by inserting addictive features into their products, while the U.S. Surgeon General is touring the nation to bring awareness to the growing epidemic of loneliness and isolation. The country has endured periods of low national morale, such as in the 1970s when high inflation and the energy crisis worsened public sentiment following the Vietnam War. The current mood, however, feels different. Gallup recently reported that national mental health is at an all-time low, with few bright spots to lift spirits.
To better understand how Americans are feeling and their attitudes towards mental health in general, ThinkNow conducted a nationally representative quantitative survey of 1,500 respondents and found some interesting differences among ethnic, age and gender groups.
Technology
For example, 52% agree that technology and social media have a negative impact on mental health, but when broken out by race, 61% of Whites felt technology had a negative effect, and only 48% of Hispanics thought it did.
While technology has helped us keep in touch with friends and family in faraway places, it appears to have degraded our ability to connect in person. Staying connected online is a double-edged sword since the same news feed that brings us pictures of the grandkids and fluffy kittens also feeds us news about the wars in Israel and Ukraine, the dysfunction in Washington, the latest mass shooting and the climate crisis.
Hispanics may have a built-in defense against the isolation technology breeds, owing to their large, multigenerational households, strong social support systems, and tendency to use social media to stay connected with relatives abroad.
Age and Gender
When asked how individuals rate their mental health, men rate it higher than women by 11 percentage points, and Baby Boomers rank it highest at 83%, saying it’s good or excellent vs. 57% of Gen Z saying the same.
Gen Z spends the most amount of time on social media, so the notion that social media negatively affects mental health appears to be correlated. Unfortunately, Gen Z is also the generation that’s least comfortable discussing mental health concerns with healthcare professionals. Only 40% of them state they’re comfortable discussing their issues with a professional compared to 60% of Millennials and 65% of Boomers.
Race Affects Attitudes
As seen in previous research conducted by ThinkNow, Asian Americans lag other groups when it comes to awareness of mental health issues. Twenty-four percent of Asian Americans believe that having a mental health issue is a sign of weakness compared to the 16% average for all groups. Asians are also considerably less likely to be aware of mental health services in their communities (42% vs. 55%) and most likely to seek out information on social media (51% vs. 35%).

5 Public speaking tips from TED - Visualized summarySpeakerHub
From their humble beginnings in 1984, TED has grown into the world’s most powerful amplifier for speakers and thought-leaders to share their ideas. They have over 2,400 filmed talks (not including the 30,000+ TEDx videos) freely available online, and have hosted over 17,500 events around the world.
With over one billion views in a year, it’s no wonder that so many speakers are looking to TED for ideas on how to share their message more effectively.
The article “5 Public-Speaking Tips TED Gives Its Speakers”, by Carmine Gallo for Forbes, gives speakers five practical ways to connect with their audience, and effectively share their ideas on stage.
Whether you are gearing up to get on a TED stage yourself, or just want to master the skills that so many of their speakers possess, these tips and quotes from Chris Anderson, the TED Talks Curator, will encourage you to make the most impactful impression on your audience.

ChatGPT and the Future of Work - Clark Boyd Clark Boyd
Everyone is in agreement that ChatGPT (and other generative AI tools) will shape the future of work. Yet there is little consensus on exactly how, when, and to what extent this technology will change our world.
Businesses that extract maximum value from ChatGPT will use it as a collaborative tool for everything from brainstorming to technical maintenance.
For individuals, now is the time to pinpoint the skills the future professional will need to thrive in the AI age.
Check out this presentation to understand what ChatGPT is, how it will shape the future of work, and how you can prepare to take advantage.
A brief introduction to DataScience with explaining of the concepts, algorithms, machine learning, supervised and unsupervised learning, clustering, statistics, data preprocessing, real-world applications etc.
It's part of a Data Science Corner Campaign where I will be discussing the fundamentals of DataScience, AIML, Statistics etc.

지 속성으로 이것을 표현하는데,
재질이란것은 빛을 받을때 반사되는 정도를 저 세가지 속성으로
표현한 것입니다.
물론 저 세가지 속성은 빛도 마찬가지로 가지고 있습니다.
따라서 빛 * 물체의 재질 = 화면상에 표현되는 색상 이라고 생각하
