The problem of action-conditioned image prediction in robotics is to predict the expected next frame given the current camera frame the robot observes and the action it selects. We provide the first comparison of two recent popular models, Convolutional Dynamic Neural Advection (CDNA) (Finn et al., 2016) and a feedforward model (Oh et al., 2015), especially for image prediction on cars. Our maj...

In Compressed Sensing (CS) of MRI, optimization of the regularization parameters is not a trivial task. We aimed to establish a method that could determine the optimal weights for regularization parameters in CS of time-of-flight MR angiography (TOF-MRA) by comparing various image metrics with radiologists' visual evaluation. TOF-MRA of a healthy volunteer was scanned using a 3T-MR system. Imag...

IEEE 802.11 wireless local area networks (WLANs) are now a days used extensively in our daily life, which provides the wide variety of multimedia applications like IPTV, video Conferencing, VOIP etc. IEEE 802.11e was developed by IEEE working group as an enhancement to IEEE 802.11 and it provides a prioritized and good service differentiation but could not able to provide the desired quality of...

Visual Display Units (VDUs), capable of displaying video data at High Definition (HD) and Ultra HD (UHD) resolutions, are frequently employed in a variety of technological domains. Quantization-induced video compression artifacts, which are usually unnoticeable in low resolution environments, are typically conspicuous on high resolution VDUs and video data. The default quantization matrices (QM...

The RGB color retinal image has an interesting characteristic, i.e. the G channel contains more important information than the other ones. One of the most important features in a retinal image is the retinal blood vessel structure. Many diseases can be diagnosed based on in the retinal blood vessel, such as micro aneurysms that can lead to blindness. In the G channel, the contrast between retin...

PURPOSE Slice encoding for metal artifact correction acquires a three-dimensional image of each excited slice with view-angle tilting to reduce slice and readout direction artifacts respectively, but requires additional imaging time. The purpose of this study was to provide a technique for faster imaging around metallic implants by undersampling k-space. METHODS Assuming that areas of slice d...

Advances in imaging and computing hardware have led to an explosion in the use of color images in image processing, graphics and computer vision applications across various domains such as medical imaging, satellite imagery, document analysis and biometrics to name a few. However, these images are subjected to a wide variety of distortions during its acquisition, subsequent compression, transmi...

Temporal pooling and temporal defects are the two di erences between image and video quality assessment. Whereas temporal pooling has been the object of two recent studies, this paper focuses on the rarely addressed topic of compression-induced temporal artifacts, such as mosquito noise. To study temporal aspects in subjective quality assessment, we compared the perceived quality of two version...
