WATERMARKING CITRA DIGITAL BERWARNA MENGGUNAKAN STATIONARY WAVELET TRANSFORM (SWT)

Ilkom Jurnal Ilmiah, 2019
Digital Image watermarking is widely used and studied for ownership identification, data protection, and authentication. A good watermarking scheme should achieve the watermarking requirements such as imperceptibility, robustness and capacity.

Deep learning‐based super‐resolution reconstruction and improved YOLOv9 for efficient benthos detection: a case study at Lake Hamana, Japan

Remote Sensing in Ecology and Conservation, EarlyView.
This study presents a UAV‐based framework that integrates deep learning‐based super‐resolution reconstruction and an enhanced YOLO detector to improve centimetre‐scale benthic organism monitoring. Using hermit crabs in Lake Hamana, a coastal lagoon in Japan, as a case study, the method substantially enhanced small‐object detection performance ...

A Retinomorphic Graphene Transistor Implementing Direction‐ and Velocity‐Selective Computation for In‐Sensor Image Stabilization

Small, EarlyView.
A multi‐gated ion‐gel graphene transistor architecture emulates spatiotemporal dendritic filtering inspired by biological direction‐selective retinal circuits. Leveraging distributed resistance‐capacitive ionic relaxation delays under combined excitation‐inhibition pulse routines, the solid‐state device exhibits programmable direction‐selective index ...

Improving PSNR and computational efficiency in orthogonal ghost imaging

Scientific Reports
In this paper, we present an orthogonal ghost imaging (OGI) method based on two-dimensional discrete cosine transform (2D-DCT) patterns. Unlike traditional methods that are based on random or sinusoidal patterns, our method relies on structured orthogonal patterns to enhance both image quality and reconstruction speed, outperforming random and ...

Robust steganographic framework for securing sensitive healthcare data of telemedicine using convolutional neural network

CAAI Transactions on Intelligence Technology, EarlyView.
Abstract Data is the key element that runs the modern society. Large amounts of data are being released day by day as a result of many activities. The digital data is transferred through the Internet which may be vulnerable to attacks while transmitting. Especially, the medical data is observed to be of at most importance.

VDNeRF: Vision‐Only Dynamic Neural Radiance Field for Urban Scenes

CAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Neural radiance fields (NeRFs) implicitly model continuous three‐dimensional scenes using a set of images with known camera poses, enabling the rendering of photorealistic novel views. However, existing NeRF‐based methods encounter challenges in applications such as autonomous driving and robotic perception, primarily due to the difficulty of ...

DrLS: Distortion‐Resistant Lossless Steganography via Colour Depth Interpolation

CAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT The lossless data steganography is to hide a certain amount of information into a container image. Previous lossless steganography methods fail to strike a balance between capacity, imperceptibility, accuracy, and robustness, commonly vulnerable to distortion on container images.
