We introduce a novel method for evaluating the pupil light reflex (PLR) response using digital video recordings. Expensive, specialized devices are replacing traditional penlight tests in emergency ...

Abstract: Identifying edges is a crucial foundational step in many image processing techniques, including those applied to tasks like image enhancement, segmentation, object tracking, and video or ...

In the realm of image processing, noise reduction often comes at the cost of losing critical details like edges. This is where bilateral filtering shines—a powerful technique that balances noise ...

Abstract: As video data continues to grow, the burden on network transmission increases significantly. Efficient video compression techniques are crucial to meet the rising demand for multimedia ...

Presented here is a MATLAB-based program for image compression using discrete cosine transform technique. It works for both coloured and grayscale images. Over the last few years, messaging apps like ...

An effective method for compression of ECG signals, which falls within the transform lossy compression category, is proposed. The transformation is realized by a fast wavelet transform. The ...

Audio frequencies range from 20Hz to 20kHz but these frequencies are not heard in the same way. Frequencies below 20Hz and above 20kHz are very difficult to hear, while those not much more than 20Hz, ...
