Hanan Selman Hessan and Ahmed Mohammed Abbas 563 Abstract Immune status was examined after tonsillectomy operations in 30 children with recurrent acute tonsillitis, their ages ranged between 3-10 years, were clinically diagnosed by ENT surgeon at AlHilla General Teaching Hospital and 10 apparently healthy children were included as a control in the study which lasted from February to May 2011 .I...

This work presents a robust online learning and recognition system. The basic idea is to exploit information from tracking an object during the recognition and/or learning stage to obtain increased robustness and better recognition results. Object tracking by means of an extended MSER tracker is utilized to detect local features and construct their trajectories. Compact object representations a...

Extraction of text embedded in scene images has many applications, such as license plate recognition, content based retrieval, text based indexing etc. As the appearances of the text in images are unpredictable, separating text pixels from the background is a challenging one. A new frame work is introduced here which uses edge enhanced MSER along with connected components for text extraction. C...

In a comprehensive study of methods for dealing with the problem of the initial transient, Hoad et al. (2008) determined that the MSER (White, 1997) was an efficient and effective truncation rule appropriate for automation. In this paper, we suggest that the MSER works well because it minimizes an approximation to the mean-squared error in the estimated steady-state mean. Using the example of a...

Larvae of many intertidal species develop offshore and must cross the surf zone to complete their onshore migration to adult habitats. Depending on hydrodynamics, the surf zone may limit this migration, especially on reflective rocky shores. As a logistically tractable analog of a rocky shore environment, we carried out a comprehensive biological and physical study of the hydrodynamics of a ste...

Detection of local features which are distinctive, invariant and discriminative is used to construct compact image representations in many computer vision applications. Achieving robustness against viewpoint change motivated the development of affine invariant detectors responding to image gradient or contrast changes, edges or corners. We focus on the Maximally Stable Extremal Regions (MSER) d...

The human Surf-1 and Surf-2 genes are divergently transcribed and share a single bi-directional promoter. The addition of serum growth factors to serum-starved cells activates transcription in the Surf-1 direction, but has no effect on transcription in the Surf-2 direction. Mutations that block the binding of YY1 to a site immediately downstream of the major Surf-1 transcription start point abo...
