Web27. nov 2024 · We study the problem of symmetry detection of 3D shapes from single-view RGB-D images, where severely missing data renders geometric detection approach infeasible. We propose an end-to-end deep neural network which is able to predict both reflectional and rotational symmetries of 3D objects present in the input RGB-D image. In mathematics, reflection symmetry, line symmetry, mirror symmetry, or mirror-image symmetry is symmetry with respect to a reflection. That is, a figure which does not change upon undergoing a reflection has reflectional symmetry. In 2D there is a line/axis of symmetry, in 3D a plane of symmetry. An object or … Zobraziť viac In formal terms, a mathematical object is symmetric with respect to a given operation such as reflection, rotation or translation, if, when applied to the object, this operation preserves some property of the object. The … Zobraziť viac Animals that are bilaterally symmetric have reflection symmetry in the sagittal plane, which divides the body vertically into left and right halves, with one of each sense organ and limb pair on either side. Most animals are bilaterally symmetric, likely because this … Zobraziť viac • Patterns in nature • Point reflection symmetry • Coxeter group theory of Reflection groups in Euclidean space • Rotational symmetry (different type of symmetry) Zobraziť viac Triangles with reflection symmetry are isosceles. Quadrilaterals with reflection symmetry are kites, (concave) deltoids, rhombi, and isosceles trapezoids. All even-sided polygons have two simple reflective forms, one with lines of reflections through vertices, … Zobraziť viac For more general types of reflection there are correspondingly more general types of reflection symmetry. For example: • with respect to a non-isometric affine involution Zobraziť viac Mirror symmetry is often used in architecture, as in the facade of Santa Maria Novella, Florence.
