Object re-identification, such as vehicle re-identification or pedestrian plays a significant role in intelligent video surveillance systems for public security. Due to viewpoint variations and appearance changes, both pedestrians vehicles usually have complex intra-class variations. However, most existing object methods often use sample-level triplet loss function cooperating with single-proxy...

Objective(s): We evaluated edge artifacts in relation to phantom diameter and reconstruction parameters in point spread function (PSF)-based positron emission tomography (PET) image reconstruction.Methods: PET data were acquired from an original cone-shaped phantom filled with 18F solution (21.9 kBq/mL) for 10 min using a Biograph mCT scanner. The images were reconstructed using the baseline or...

The Problem: To develop a model of the key characteristics of inferotemporal cortex (IT) as a prerequisite for understanding monkey/human object recognition.

We present a method for estimating the size, and consequently eeort and duration , of object oriented software development projects. Diierent estimates may be made in diierent phases of the development process, according to the available information. We deene an adaptation of traditional function points, called \Object Oriented Function Points", to enable the measurement of object oriented anal...

Although young children often rely on salient perceptual cues, such as shape, when categorizing novel objects, children shift towards deeper relational reasoning when they compare category members or attend to functional properties. In this study, we investigated the independent and combined effects of comparison and function in children’s categorization of novel objects. Across two experiments...
