  • We present a joint model for Chinese word segmentation and new word detection. We present high dimensional new features, including word-based features and enriched edge (label-transition) features, for the joint modeling. As we know, training a word segmentation system on large-scale datasets is already costly.

  • This worksheet is an introduction on how to handle images in Matlab. When working with images in Matlab, there are many things to keep in mind such as loading an image, using the right format, saving the data as different data types, how to display an image, conversion between different image formats, etc. This worksheet presents some of the commands designed for these operations. Most of these commands require you to have the Image processing tool box installed with Matlab.

  • Over the last two decades, we have witnessed an explosive growth in both the diversity of techniques and the range of applications of image processing. However, the area of color image processing is still sporadically covered, despite having become commonplace, with consumers choosing the convenience of color imaging over traditional grayscale imaging.

  • The background to the contents of this thesis is my position as a Patent Engineer at Ericsson AB, where I am responsible for the patenting of innovations within the technology area of DRM. A need for an overview of DRM indicating the innovation trends was identified. The thesis is of interest for Ericsson’s patent & licensing development, as well as for development engineers working and innovating within DRM at Ericsson.

  • In the last two decades, fractional (or non integer) differentiation has played a very important role in various fields such as mechanics, electricity, chemistry, biology, economics, control theory and signal and image processing. For example, in the last three fields, some important considerations such as modelling, curve fitting, filtering, pattern recognition, edge detection, identification, stability, controllability, observability and robustness are now linked to long-range dependence phenomena. Similar progress has been made in other fields listed here.

  • Image Segmentation and Edge Detection What is this chapter about? This chapter is about those Image Processing techniques that are used in order to prepare an image as an input to an automatic system. These techniques perform vision image segmentation and edge detection, and their purpose is to extract information from an image in such a way that the output image contains much less information than the original one, but the little information it contains is much more relevant to the other modules of an automatic vision system than the discarded information. ...

  • EDGE DETECTION Changes or discontinuities in an image amplitude attribute such as luminance or tristimulus value are fundamentally important primitive characteristics of an image because they often provide an indication of the physical extent of objects within the image. Local discontinuities in image luminance from one level to another are called luminance edges. Global luminance discontinuities, called luminance boundary segments, are considered in Section 17.4.

  • Business information systems professionals are creative people working at the cutting edge of innovation. Your studies will teach you what types of information you’ll need to do this job, how you’ll need it presented and why you’ll need it at all. We’ll also teach you team skills by asking you to work in teams to complete some problems. This is the way information systems operate in businesses and other organisations.

  • All this is why HDTV was an enthusiast’s dream come true—a dream that Sony was first to realize with the Qualia™ 004, the world’s first digital home theater projector with full 1920 x 1080 resolution. Thanks to HDTV, viewers with 20/20 vision can sit as close as 3.16 PH and still enjoy the illusion of a continuous picture. While 1080p represents the current home entertainment standard, today’s cutting edge home theaters require even more. Enthusiasts want to recreate the level of engagement they experience in modern movie theaters. That means sitting even closer than 3.

  • Digital Image Processing The electronic camera/frame grabber/computer combination has made it easy to digitize, store and manipulate images. These possibilities have made a great impact on optical metrology in recent years. Digital image processing has evolved as a specific scientific branch for many years. Many of the methods and techniques developed here are directly applicable to problems in optical metrology. In this chapter we go through some of the standard methods such as edge detection, contrast stretching, noise suppression, etc.

  • Additional reduction of the leaflet height could be achieved by folding the leaflet edge toward the ventricle before deploying the U- clip. The remaining loops were distributed at equal distance along the edge of the prolapsed segment by applying the same technique. After the pledget platform was secured, the 2 free suture needles were placed through the anterior prolapse. The correct apposition was confirmed with saline test. The assistan, at the patient side, tied the knots. Annuloplasty was performed at the surgeon's discretion.
