conclusion various filters are needed to improve the image quality. in this study, seven different filters were implemented and investigated on both noisy and noise-free images. background developmental dysplasia of the hip (ddh) can be detected with ultrasonography (usg) images. however, the accuracy of this method is dependent on the skill of the radiologist. radiologists measure the hip join...

leaving one’s parental home disrupts place attachment, described as the affective bond or link between one individual and a specific place and/or the people living in that place. in other words, because students move away from their parents, their friend and their hometown, their bonds with these people and their hometown are disrupted. although moving disrupts place attachment to their hometow...

OBJECTIVES To determine if canting of the occlusal plane influences esthetic evaluation of the smile among orthodontists, dentists and laypersons. STUDY DESIGN A frontal photo of a smile with 0 occlusal plane canting in relation to the bipupillary plane was modified using Adobe Photoshop C3 (Adobe Systems Inc, San José, California) to generate two images with occlusal plane inclinations of 2 ...

Place recognition is one of the most fundamental topics in computer vision and robotics communities, where the task is to accurately and efficiently recognize the location of a given query image. Despite years of wisdom accumulated in this field, place recognition still remains an open problem due to the various ways in which the appearance of real-world places may differ. This paper presents a...

ion levels for image fusion The fusion of an image series can take place on different abstraction levels (Fig. 1): • Within a data-level fusion (pixel-level fusion), the combination takes place at the level of the image data, i.e. the gray or RGB values. The precondition of a data fusion is that the images have been recorded with homogeneous sensors.

Modern psychological theories of spatial cognition postulate the existence of a ‘geometric module’ for reorientation. This concept is derived from experimental data showing that in rectangular arenas with distinct landmarks in the corners, disoriented rats often make diagonal errors, suggesting their preference for the geometric (arena shape) over the non-geometric (landmarks) cues. Moreover, e...
