Image Segmentation Using Active Contours with Hessian-Based Gradient Vector Flow External Force

Qianqian Qian, Ke Cheng, Wei Qian, Qingchang Deng et al. • Sensors (2022)

The gradient vector flow (GVF) model has been widely used in the field of computer image segmentation. In order to achieve better results in image processing, there are many research papers based on the GVF model. However, few models includ...

LatentColorization: Latent Diffusion-Based Speaker Video Colorization

Rory Ward, Dan Bigioi, Shubhajit Basak, John G. Breslin et al. • IEEE Access (2024)

While current research predominantly focuses on image-based colorization, the domain of video-based colorization remains relatively unexplored. Many existing video colorization techniques operate frame-by-frame, often overlooking the critic...

Fourier Truncation Regularization Method for a Time-Fractional Backward Diffusion Problem with a Nonlinear Source

Fan Yang, Ping Fan, Xiao-Xiao Li, Xin-Yi Ma • Mathematics (2019)

In present paper, we deal with a backward diffusion problem for a time-fractional diffusion problem with a nonlinear source in a strip domain. We all know this nonlinear problem is severely ill-posed, i.e., the solution does not depend cont...
