The successful restoration of old-growth-like loblolly (Pinus taeda) and shortleaf (Pinus echinata) pine-dominated forests requires the integration of ecological information with long-term silvicultural research from places such as the Crossett Experimental Forest (CEF). Conventional management practices such as timber harvesting or competition control have supplied us with the tools for restor...

To solve the problem of CT image degradation, a double regularization CT image blind restoration reconstruction method was proposed. The objective function including both a clear image and point spread function was established. To avoid the over-smoothing phenomenon and protect the detail, the objective function includes two constraint regularization terms. They are total variation (TV) and wav...

abstract this study aimed to investigate the effects of urban wastewater on some soil physical and chemical properties in segzi, east isfahan. six sites were selected considering the planted species (haloxylon persicum and nitraria schoberi) and irrigation types (control or no irrigation, water logged and furrow irrigation methods). the 4 to 12 replications were chosen in each site depending on...

Combined effects of brush encroachment and channel entrenchment in the Southwestern United States threaten ecological, hydrological, and agricultural functions of ephemeral streams and associated alluvial surfaces. Restoration is difficult because entrenchment is widespread, and highly variable flow magnitudes defy standardized structural approaches. Methods developed by the Zuni Indians during...

Wiener filter is widely used for image denoising and restoration. It is alternatively known as the minimum mean square error filter or the least square error filter, since the objective function used in Wiener filter is an age-old benchmark called the Mean Square Error (MSE). Wiener filter tries to approximate the degraded image so that its objective function is optimized. Although MSE is consi...

Abstract Restoration of natural forests previously replaced by plantations is a widespread challenge for forestry in Chile and elsewhere. However, there little documented evidence successful restoration, either through active or passive approaches. In this study, we aimed at (1) determining the potential restoration first-rotation Pinus radiata regeneration native tree species (2) identifying d...

In digital photography, two image restoration tasks have been studied extensively and resolved independently: demosaicing and super-resolution. Both these tasks are related to resolution limitations of the camera. Performing superresolution on a demosaiced images simply exacerbates the artifacts introduced by demosaicing. In this paper, we show that such accumulation of errors can be easily ave...
