Higher Image Retrieval Efficiency Using Color Features
Image retrieval techniques are useful in many image processing applications. Content based image retrieval systems works with whole images and searching is based on comparison of the query. In this paper we present a novel frame work for the color information and achieve higher retrieval efficiency using dominant color feature. An image is partitioned into sub blocks of equal size as a first step. Color of each sub block is extracted by using the RGB color space. A one to one matching scheme is used to compare the query and target images. Minkowski distance is used to retrieving the similar images. The experimental results demonstrate the efficiency of the method
Facial expressions recognition based on dimensionality reduction techniques
Interest in image retrieval has increased in large part due to the rapid growth of the World Wide Web. The traditional text based search and retrieval has its own limitations and hence we move to a facial expressions images are search and retrieval system. In this paper we present a facial expression retrieval system that takes an image as the input query and retrieves images based on image content. Face recognition system is recognizing based on dimensionality reduction derived image features. Facial expressions recognition is the application of computer vision to the image retrieval problem. In this recognition context might refer colours, shapes, textures, or any other information that can be derived from the image itself
HANDHELD MONEY DEPOSIT AND WITHDRAWAL CELL BANKING GADGET
The primary concept of the micro-bank product is the financial institution should employ special persons which are licensed because the business correspondents (BC) to hold a micro-bank machine together. Each Business correspondents will most likely be allotted to a particular handheld guaranteed electronic doorstep banking system machine. The bankās commensurate huge clientele isnāt inside the urban level however, inside the frequently pretermitted rural areas. The micro-bank technique is always attached to the central banking server using GSM communication. During this paper an assured handheld doorstep banking industry proven to as Micro-bank machine should certainly grant plan to totally free styles in rural areas and remote places for example cities. The micro-bank machine that will get the OTP information will record breaking speed of the feel of this message. Light tasks like acquiring away and off to the ATM and retreating cash cause humans in cities lose their operating hrs. and, consequently, miss a big live in the profit also. The look can also be operated within as well as on the far side within the regular banking hrs. The primary goal within the handheld machine should be to administer banking services like money withdrawals and money deposit while not the individual ever striving having a bank during remote areas wherever a GSM cellular association isnāt possible
Left subclavian artery coverage during thoracic endovascular aortic repair and risk of perioperative stroke or death
IntroductionLeft subclavian artery (LSA) coverage during thoracic endovascular aortic repair (TEVAR) is often necessary due to anatomic factors and is performed in to up to 40% of procedures. Despite the frequency of LSA coverage during TEVAR, reported associations with risk of periprocedural stroke or death are inconsistent in reported literature. We examined the 2005-2008 American College of Surgeons National Surgical Quality Improvement Program Participant Use Data file to determine associations between LSA coverage during TEVAR and risk of perioperative stroke or death.MethodsCurrent procedural terminology (CPT) codes were used to identify patients undergoing TEVAR, LSA coverage, and subclavian revascularization. Patients undergoing coronary bypass, ascending aortic repair, abdominal aortic aneurysm repair, or nonvascular intra-abdominal procedures during the same operation were excluded. Perioperative stroke and mortality associations with LSA coverage were examined using logistic regression models for each outcome. Significance was assessed at Ī± = 0.05, with univariable P < .05 required for multivariable model entry.ResultsEight hundred forty-five TEVAR procedures were identified, of which 52 patients were excluded due to additional major procedures performed with TEVAR. Seven hundred thirty-three of the remaining 793 procedures included CPT codes indicating primary placement of an initial thoracic endograft and form the basis of this analysis. LSA coverage occurred in 279 procedures (38%). Thirty-day stroke and mortality rates were 5.7% and 7.0%, respectively. LSA coverage was associated with increased 30-day risk of stroke in multivariable modeling (odds ratio [OR], 2.17 95% confidence interval [CI], 1.13-4.14; P = .019). Other significant multivariable risk factors for stroke included proximal aortic cuff placement during TEVAR (OR, 2.58; 95% CI, 1.30-5.16; P = .007) and emergency procedure status (OR, 3.60; 95% CI, 1.87-6.94; P < .001). No significant association between LSA coverage and perioperative mortality was identified (univariable OR, 1.70; 95% CI, 0.98-2.93; P = .0578).ConclusionLSA coverage during thoracic endovascular repair is associated with increased risk of perioperative stroke following TEVAR. Further evidence is needed to determine whether procedural modifications, including LSA revascularization, reduce the incidence of stroke associated with TEVAR
Characterization of resident surgeon participation during carotid endarterectomy and impact on perioperative outcomes
IntroductionThe impact of resident surgeon participation during vascular procedures on postoperative outcomes is incompletely understood. We characterized resident physician participation during carotid endarterectomy (CEA) procedures within the 2005-2009 American College of Surgeons National Surgical Quality Improvement Participant Use Datafile and evaluated associations with procedural characteristics and perioperative adverse events.MethodsCEAs were identified using primary current procedural terminology codes; those performed simultaneously with other major procedures or unknown resident participation status were excluded. Group-wise comparisons based on resident participation status were performed using Ļ2 or Fisher's exact test for categorical variables and t tests or nonparametric methods for continuous variables. Associations with perioperative adverse events (major = stroke, death, myocardial infarction, or cardiac arrest; minor = peripheral nerve injury, bleeding requiring transfusion, surgical site infection, or wound disruption) were assessed using multivariable logistic regression models adjusting for other known risk factors.ResultsA total of 25,280 CEA procedures were analyzed, of which residents participated in 13,705 (54.2%), while residents were absent in 11,575 (45.8%). Among CEAs with resident physician participation, resident level was categorized as junior (postgraduate year [PGY] 1-2) in 21.9%, senior (PGY 3-5) in 52.7%, and fellow (PGY ā„6) in 25.3%. Major adverse event rates with and without resident participation were 1.9% versus 2.1%, and minor adverse event rates with and without resident participation were 0.9% versus 1.0%, respectively. In multivariable models, resident physician participation was not associated with perioperative risk for major adverse events (odds ratio [OR], 0.90; 95% confidence interval [CI], 0.75-1.08) or minor adverse events (OR, 0.93; 95% CI, 0.72-1.21).ConclusionsResident surgeon participation during CEA is not associated with risk of adverse perioperative events
Origin of early maturing pigeonpea germplasm and its impact on adaptation and cropping systems
Pigeonpea breeding activities started about a century ago and for decades only late maturing cultivars dominated the global cultivation. Historically, no early maturing cultivar was available for a very long time and breeding of such varieties started in the third quarter of 20th century but at a low key. From these efforts, some pigeonpea varieties maturing in 90ā150 days were bred. Information gathered from various sources revealed that the first few early maturing genotypes originated through spontaneous mutations in the late maturing fieldāgrown landraces. In other cases, transgressive segregation and induced mutations also produced early maturing varieties. At present, the high yielding early maturing cultivars are contributing significantly towards widening the adaption barriers and in the diversification of some ageāold cropping systems. In this paper, the authors, besides discussing the importance of early maturing cultivars in present agricultural systems, also summarize information related to the origin of primary sources of earliness
