Image & Video processing Flashcards
What is image processing ?
Image processing is the technique of manipulating images to achieve desired effects, improve quality, or extract information. This manipulation ranges from simple tasks like adjusting brightness and contrast to more complex operations such as object detection, image segmentation, and color correction.
What is GPU?
GPUs are designed to handle parallel processing, making them exceptionally well suited for computationally intensive image and video processing tasks. In image processing, GPUs accelerate operations such as filtering, transformation, and complex algorithmic manipulations.
What is DSP?
It is real-time processing of high resolution images is a subfield of digital signal processing or DSP. DSP is used in a wide range of areas,
including medical imaging, surveillance, and computer vision.
What are the benefits of GPU?
For video processing, the benefits of using GPUs are even more pronounced. The encoding and decoding of video streams, crucial for video playback and streaming, are significantly accelerated by GPUs. Furthermore, advanced video editing tasks that involve effects, transitions,
and color grading benefit from the parallel processing power of GPUs, reducing rendering times and enhancing the workflow efficiency for video editors. The beginning of machine learning and deep learning has further expanded the role of GPUs in image and video processing. GPUs are at the heart of training complex models for tasks such
as automated image enhancement, object detection, and even generating synthetic media content. Their ability to perform a vast number of calculations simultaneously makes them ideal for the heavy computational demands of these advanced algorithms.
What are some image formats?
-JPEG
-PNG
-GIF
What are some autoimage processing?
OpenCV, or Open source Computer Vision Library, and PIL, or Python Imaging Library
What is bitrate?
It is the amount of data processed per second of video, directly influencing file size and quality, and resolution, which determines the detail and clarity of the video image. Similar to image formats, different video formats cater to various needs.
What programs offer degrees of video quality and management?
First is MP4 or MPEG-4 part 14, renowned for its balance of quality and compatibility. Second is AVI or audio video interleave, which stands out for its minimal compression, ensuring high quality at the cost of larger file sizes. Another commonly used video format is MOV, a quick time file format developed by Apple. MOV is known for its high quality and compatibility with iOS devices.
What are some video editing and compression software?
Software such as Adobe Premiere Pro, Final Cut Pro, and Handbrake are indispensable tools for creators. These tools allow one to craft compelling visual narratives, optimize videos for streaming, and compress files for efficient distribution without significant loss of quality.
Whats the difference in software and harware in image & video processing?
While software provides the tools necessary for image and video processing, hardware, particularly the graphics processing unit or GPU, plays a fundamental role in executing these tasks efficiently.
