background and objectives: tree nuts and their oils contain bioactive materials which have vital roles in improving human’s health. degradation and decreasing the quality of the nuts especially in almond which have high fat is related to the oxidation. the quality of stored almond depends mainly on the kernel moisture and fat , storage temperature, relative humidity, oxygen level, type of packa...

Shape knowledge indexing is crucial in design reuse and knowledge engineering, in which the pivot issue is to establish the unique representation of the invariant shape properties. In this paper we present a local shape-indexing scheme defined on the Fourier spectrum of the shape distribution. We theoretically prove that our shape code is strictly invariant of affine transformations, and be sui...

Dolenec, Z.: Breeding characteristics of the barn swallow (Hirundo rustica) in NW Croatia. Nat. Croat., Vol. 11, No. 4., 439–445, 2002, Zagreb. The research was carried out in the village of Mokrice (46°00'N, 15°55'E) in NW Croatia during 1998–1999. Egg length averaged 19.16 mm, egg breadth 13.72 mm, egg volume 1840.8 mm3, egg shape index 1.40 and egg weight 1.81 g (during both years). The nest...

background: the foramen magnum (fm) is an important landmark of the skull base and a transition zone between spine and skull as well as its close relationship to the brain and the spinal cord. so the fm has gained considerable interest due to its comparative anatomy, ontogeny, clinical, and animal breeding viewpoints. objectives: the aim of this study was to determine morphology and morphometry...

Performance of an image or video database is directly related to indexing performance. Proposed indexing methods usually rely on low-level features such as color, texture and shape information extracted from an image or a key-frame selected within a shot, which are very sensitive to small changes in intensity or lightning conditions. In this study, we show that one can extract more robust and r...

this study investigates skull variation in persian jird, meriones persicus (blanford, 1875) in relation to the geoclimatical conditions across its distribution range. the pattern of correlations between geoclimatical variables and geometric shape descriptors for 221 ventral crania was studied by landmark-based geometric morphometric techniques. the covariation between shape and geoclimatical va...
