Recently developed landmark-based geometric morphometry has been used to depict the morphological development of organisms. In geometry, four landmarks can be mapped to any other four by Möbius transformations, if the cross-ratio of the landmarks is invariant and vice versa. To geometrically analyze the morphological development of the human body, we examined the cross-ratio of three consecutiv...

This paper presents a framework to simultaneously segment and track multiple body parts of interacting humans in the presence of mutual occlusion and shadow. The framework uses multiple free-form blobs and a coarse model of the human body. The color image sequence is processed at three levels: pixel level, blob level, and object level. A Gaussian mixture model is used at the pixel level to trai...

We experiment with interactive machine learning for mouse behavior classification, following the pioneering work JAABA [1]. Here, we describe a simple image processing pipeline that allows extracting individual body parts from single mouse top view video. Our experiments show that behavior classification accuracy increases substantially when transitioning from wholebody descriptors to features ...

In order to track and recognize the movements of multiple people using multiple cameras, each person needs to be segmented and identified in the image of each camera. We propose a method that tracks multiple people and identifies their body parts in multiple camera images. Estimation of the human positions and identification among the multiple cameras is mainly based on the silhouettes method c...

Latin et mis en bel ordre par questions et responses pour la facilite des jeunes etudians en Chirurgie' (par A.E.B.D.C.I. Paris 1659). This title perhaps best epitomizes the significance attached to Galen's masterpiece on physiology and its anatomical basis. It shows its use as the authoritative textbook for students in general and those of surgery in particular. The edition of the version cite...

In this issue of Neuron, Orlov et al. show that the human occipitotemporal cortex contains regions responding preferentially to body part categories, such as upper limbs (hand, elbow), torsos, or lower faces (mouth, chin). This organization may reflect differences in the connectivity of these regions with other brain regions, to support the efficient processing of the different types of informa...

Recent studies on the compartmentalization of fly mushroom bodies show that learning and memory in Drosophila are not as simple as might be expected for an organism with such a tiny brain.

Hox proteins shape animal structures by eliciting different developmental programs along the anteroposterior body axis. A recent study reveals that the Drosophila Hox protein Deformed directly activates the cell-death-promoting gene reaper to maintain the boundaries between distinct head segments.

Neuropsychological studies suggest that patients with left parietal lesions may show impaired localization of parts of either their own or the examiner's body, despite preserved ability to identify isolated body parts. This deficit, called autotopagnosia, may result from damage to the Body Structural Description (BSD), a representation which codes spatial relationships among body parts. We used...

Women with high body dissatisfaction look less at their 'beautiful' body parts than their 'ugly' body parts. This study tested the robustness of this selective viewing pattern and examined the influence of positive body exposure on body-dissatisfied women's attention for 'ugly' and 'beautiful' body parts. In women with high body dissatisfaction (N = 28) and women with low body dissatisfaction (...
