This paper examines the methods used by the Bank of Japan for the estimation of the output gap. Attention is paid to the real-time estimation problem. After reviewing the evolution of output gap estimation at the Bank, I discuss advantages and disadvantages of the various output gap measures. First, I examine the usefulness of the output gap for inflation forecasting and show that the real-time...

This paper presents a robust algorithm for segmentation of moving objects in video, that first solves the global camera motion estimation problem and then processing the local object motion using the global motion parameters. This is work in progress. Key Words-Camera motion, global motion, extraction, segmentation

We develop a technique for generating smooth and accurate 3D human pose motion estimates from RGB video sequences. Our method, which we call Motion Estimation via Variational Autoencoder (MEVA), decomposes temporal sequence of into representation using auto-encoder-based compression residual learned through refinement. This two-step encoding captures in two stages: general estimation step that ...

The proliferation of high powered computers, the availability of high quality & inexpensive video cameras & the increasing need for automated video analysis has generated a great deal of interest in object tracking. In this regard object tracking based on Motion Estimation which is a popular technique for computing the displacement vectors between object and motion capture. Motion is very impor...

The estimation of visual motion has long been studied as a paradigmatic neural computation, and multiple models have been advanced to explain behavioral and neural responses to motion signals. A broad class of models, originating with the Reichardt correlator model, proposes that animals estimate motion by computing a temporal cross-correlation of light intensities from two neighboring points i...

Noises, in the form of false motion vectors, cannot be avoided while capturing block motion vectors using blockbased motion estimation techniques. Similar noises are further introduced when the technique of global motion compensation is applied to obtain “true” object motion from video sequences, where both the camera and object motions are present. We observe that the performance of the mean a...

H.264/AVC video coding standard performs motion estimation using various motion partition sizes. It has been shown to improve the coding gain. However, video coding using blocks bigger than 16×16 pixels can provide a substantial coding gain compared to H.264/AVC, especially when applied to high definition video sequences. Even if coding efficiency is improved, the complexity of motion estimatio...

Motion estimation algorithms play a key role in picture-rate up-conversion. To realise high quality interpolated images, while keeping the processing requirements low, we analyse the following parameters of the motion estimation algorithm: The number of motion estimation iterations per input image pair and the image scanning order of individual iterations. Furthermore, we tackle the issue of th...
