Evaluating the effective resolution of enhanced resolution SMAP brightness temperature image products

Downscaling of coarse-resolution radiometer brightness temperature by high-resolution radar backscatter

Given the importance of soil moisture for hydrological applications, such as weather and flood forecasting, passive microwave remote sensing is a promising approach for retrieving soil moisture due to its high sensitivity to near-surface soil moisture, applicability to all weather conditions, direct relationship with the soil dielectric constant, and reduced effects from vegetation and roughnes...

Improving Super-resolution Techniques via Employing Blurriness Information of the Image

Super-resolution (SR) is a technique that produces a high resolution (HR) image via employing a number of low resolution (LR) images from the same scene. One of the degradations that attenuates performance of the SR is the blurriness of the input LR images. In many previous works in the SR, the blurriness of the LR images is assumed to be due to the integral effect of the image sensor of the im...

image resolution in the digital era: notion and clinical implications

digital radiographs need additional metadata in order to be accurate when being converted to analog media. resolution is a major reason of failures in proper printing or digitizing the images. this letter shortly explains the overlooked pitfalls of digital radiography and photography in dental practice, and briefly instructs the reader how to avoid or rectify common problems associated with res...

Evaluation of the SMAP brightness temperature downscaling algorithm using active–passive microwave observations

The effect of focal spot size on the spatial resolution of variable resolution X-ray CT scanner

Background: A variable resolution X-ray (VRX) CT scanner provides a great increase in the spatial resolution. In VRX CT scanners, the spatial resolution of the system and its field of view (FOV) can be changed according to the object size. One of the main factors that limit the spatial resolution of VRX CT scanner is the effect of the X-ray focal spot. Materials and Methods: A theoreti...
