What is Scaling and Upscaling
In computer graphics and digital image processing, scaling refers to the resize of a digital image. In video technology, the enlargement of digital material is also referred to as upscaling or resolution enhancement. When scaling a vector graphic, the graphic primitives that make up the vector graphic are stretched by geometric transformation before rasterization, which does not cause any loss of … [Read more...]
What is Mutex? Explained With Example
The term mutual exclusion or mutex (abbreviation for mutual ual exclusion) refers to a group of procedures with which the problem of the critical section is solved. Mutex methods prevent concurrent processes or threads from changing shared data structures in an uncoordinated manner at the same time or in a temporally entangled manner, which can cause the data structures to become inconsistent, … [Read more...]
How to Safeguard From Deepfake Frauds
As advancements in artificial intelligence (AI) and machine learning continue to evolve, so too does the threat landscape, with deepfake technology emerging as a potent tool for malicious actors. Deepfakes are realistic-looking media content (photo, audio, video, etc.) that has been altered, generated or falsified by artificial intelligence (AI) techniques. Although media manipulation is not a new … [Read more...]
