A novel method is given for content-aware video resizing, i.e. targeting video to a new resolution (which may involve aspect ratio change) from the original. We precompute a per-pixel cumulative shrinkability map which takes into account both the importance of each pixel and the need for continuity in the resized result. (If both x and y resizing are required, two separate shrinkability maps ar...

Abstract— Image interpolation is widely used in many image processing applications, such as digital camera, mobile phone, tablet and display devices. Image interpolation is a method of estimating the new data points within the range of discrete set of known data points. Image interpolation can also be referred as image scaling, image resizing, image re-sampling and image zooming. This paper pre...

Image scaling, fundamental task of numerous image processing and computer vision applications, is the process of resizing an image by pixel interpolation. Image scaling leads to a number of undesirable image artifacts such as aliasing, blurring and moiré. However, with an increase in the number of pixels considered for interpolation, the image quality improves. This poses a quality-time trade o...

Resizing to a lower resolution can alter the appearance of an image. In particular, downsampling an image causes blurred regions to appear sharper. It is useful at times to create a downsampled version of the image that gives the same impression as the original, such as for digital camera viewfinders. To understand the effect of blur on image appearance at different image sizes, we conduct a pe...

In this paper, we consider the use of a limited pipelining scheme in conjunction with a gate resizing technique to improve the optimal clock speed of a combinational logic block. Gate resizing is restricted to a small subset of the circuit, and target gates are identiied using a delay sensitivity metric introduced here. 1 Abstract In this paper, we consider the use of a limited pipelining schem...

Anecdotal evidence and press reports point to improper management of IS personnel as a key reason for failure of several IS outsourcing deals. IS outsourcing initiatives are often coupled with changes to the in-house IS function, resulting in significant changes to the rank, size and responsibilities of IS personnel (collectively termed as “IS resizing”). This research seeks to examine the issu...

Digital images are used everywhere and it is easy to manipulate and edit because of availability of various image processing and editing software. Resizing the image to a lower resolution can alter the appearance of an image. It is useful at times to create a downsampled version of the image that gives the same impression as the original. There are many methods for image downsampling. In this p...

This paper investigates the performance and proposes modifications to earlier methods for image authentication using distributed source coding. This approach works well on images that have undergone affine geometric transformations such as rotation and resizing and intensity transformations such as contrast and brightness adjustment. The results show that the improvements proposed here can be u...

Using various methods, an image manipulation can be done not only by the image manipulation itself, but also by the criminals of counterfeiters for the purpose of counterfeiting. Digital forensic techniques are needed to detect the tampering and manipulation of images for such illegal purposes. In this paper, we present an image manipulation detection algorithm using deep learning technology, w...
