28:20 Quantization
30:23 Run-length/Huffman Encoding within JPEG
32:56 How JPEG fits into the big picture of data compression
The JPEG algorithm is rather complex and in this video, we break down the core parts of the algorithm, specifically color spaces, YCbCr, chroma subsampling, the discrete cosine transform, quantization, and lossless encoding. The majority of the focus is on the mathematical and signal processing insights that lead to advancements in image compression and the big themes in compression as a whole that we can take away from it.
Animations created jointly by Nipun Ramakrishnan and Jesús Rascón.

How are Images Compressed? [46MB ↘↘ 4.07MB] JPEG In Depth
Go to http://brilliant.org/BranchEducation/ to sign up for free, and expand your knowledge. The first 200 people will get 20% off their annual premium membership.
You've probably saved 1000s of JPEG images, but do you know what exactly JPEG does? Our smartphones and cameras save images in JPEG format, furthermore, the majority of images you see on the internet are saved using JPEG compression. This format is everywhere, but do you know exactly how it works? Well in this video we're going to explore the JPEG compression format. This is a rather complicated video, so it may take watching it a few times through to understand it all.

Currently a niche codec, recent enhancements to the JPEG 2000 standard speed it up by 10x and will propel it into the mainstream.

With recent updates to the standard speeding up decode by 10X, is world domination around the corner ? This talk will describe many of the sophisticated features that JPEG 2000 offers, and discuss why a 20 year old standard may be the codec of the future.
Released in 2000 as a potential replacement for the wildly successful JPEG standard, JPEG 2000 is a versatile codec with many sophisticated features including:
- Superior compression at low bit rates
- Storage of multiple resolutions in a single bitstream
- Precise rate control without re-compression
- Lossy and lossless compression
- Progression by resolution, component, spatial region or quality
It is an essential codec in medical imaging, digital cinema and remote sensing. However, due to its high complexity, it has remained a niche codec that never gained the popularity of its predecessor.
All of this is about to change with the recently released High Throughput JPEG 2000 standard that speeds up the codec by up to 10x, while leaving almost all of its features intact. This will propel it into the mainstream, particularly in broadcast and digital cinema.
I will talk about the history of JPEG 2000, give an overview of its features and discuss the upcoming changes. I will also talk about current and planned GStreamer support for JPEG 2000.
Presented by Aaron Boxer.

Кто и когда разработал формат JPEG? Почему при сжатии изображений могут возникать артефакты? Какие преимущества у формата JPEG перед другими? Существует ли сегодня проблема сжатия картинок и насколько остро она стоит? Какие форматы сжатия изображений существуют и как они сравниваются между собой? Какой формат в своё время составлял ему конкуренцию? В чём преимущество JPEG 2000? Какие плюсы и минусы есть у нового нейросетевого формата JPEG AI? Что ожидать от технологий сжатия картинок в будущем?
Об этом рассказывает Дмитрий Ватолин, кандидат физико-математических наук, заведующий лабораторией компьютерной графики и мультимедиа факультета вычислительной математики и кибернетики МГУ имени М. В. Ломоносова и лабораторией интеллектуального анализа видео Института искусственного интеллекта МГУ, создатель получившего мировое признание в области сжатия данных проекта compression.ru

You've probably saved 1000s of JPEG images, but do you know what exactly JPEG does? Our smartphones and cameras save images in JPEG format, furthermore, the majority of images you see on the internet are saved using JPEG compression. This format is everywhere, but do you know exactly how it works? Well in this video we're going to explore the JPEG compression format. This is a rather complicated video, so it may take watching it a few times through to understand it all.
