In this paper we propose a method for transfer learning of endoscopic images. For transferring between features obtained from images taken by different (old and new) endoscopes, we extend the Max–Margin Domain Transfer (MMDT) proposed by Hoffman et al. in order to use L2 distance constraints as regularization, called Max–Margin Domain Transfer with L2 Distance Constraints (MMDTL2). Furthermore,...

In five dogs (18 to 28 kg) under pentobarbital anesthesia metal clips were placed on the free margin of the anterior and posterior mitral valve leaflets, and on the epicardial surface of the left ventricle at the apex and at the base. After full recovery cineangiograms were taken in the right anterior oblique and right lateral position and the length from the apex of the left ventricle to the f...

Purpose : A new method of calibration of the displacement of the cornea1 reflex in relation to the angular deviation was carried out on a population of normal subjects. Methods : The position of the cornea1 reflex was studied in 15 normal adult subjects, emmetropic and orthophoric. Each eye, photographed individually, was situated perpendicularly at the zero of a tangential scale. Slides taken ...

We present a sample re-weighting scheme inspired by recent results in margin theory. The basic idea is to add to the training set replicas of samples which are not classified with a sufficient margin. We prove the convergence of the input distribution obtained in this way. As study case, we consider an instance of the scheme involving a 1-NN classifier implementing a Vector Quantization algorit...

This paper presents a new method for viewpoint invariant pedestrian recognition problem. We use a metric learning framework to obtain a robust metric for large margin nearest neighbor classification with rejection (i.e., classifier will return no matches if all neighbors are beyond a certain distance). The rejection condition necessitates the use of a uniform threshold for a maximum allowed dis...

The literature reports an annual incidence of 5,900 cases of anal cancer in the developed countries. These involve three different anatomic zones: carcinoma of the anal canal, perianal carcinoma (formerly known as carcinoma of the anal margin, located at a distance of less than 5cm from the anal margin), and carcinoma of the perianal skin (at a distance greater than 5cm from the anal margin). B...

We revisit the task of learning a Euclidean metric from data. We approach this problem from first principles and formulate it as a surprisingly simple optimization problem. Indeed, our formulation even admits a closed form solution. This solution possesses several very attractive properties: (i) an innate geometric appeal through the Riemannian geometry of positive definite matrices; (ii) ease ...

BACKGROUND Double eyelid blepharoplasty is one of the most popular facial cosmetic surgeries performed in patients with Asian eyelids. Although most patients choose to undergo blepharoplasty for cosmetic purposes, rather than functional reasons, these patients frequently present with concomitant mild-to-moderate blepharoptosis. OBJECTIVES Performing nonincisional double eyelid surgery without...
