JPG, PNG and BMP image compression using discrete cosine transform
This paper proposes image compression using discrete cosine transform
(DCT) for the format of joint photographic expert groups (JPEG) or JPG,
portable network graphic (PNG) and bitmap (BMP). These three extensions
are the most popular types used…

Applying convolutional neural networks for limited-memory application
Currently, convolutional neural networks (CNN) are considered as the most
effective tool in image diagnosis and processing techniques. In this paper, we
studied and applied the modified SSDLite_MobileNetV2 and proposed a
solution to always…
