A scale invariant 3D object detection method based on phase Fourier transform (PhFT) is addressed. Three-dimensionality is expressed in terms of range images. The PhFT of a range image gives information about the orientations of the surfaces in the 3

In this paper a unique map or signature of three dimensional objects is defined. The map is obtained locally, for every possible rotation of the object, by the Fourier transform of the phase-encoded range-image at each specific rotation. From these l

Three-dimensional object recognition with scale and rotation changes is addressed. The recognition method is described in terms of correlations between spherical surfaces. Tridimensionality is codified into range images. We used the phase Fourier tra

Invariant optical correlation method for 3D target detection is addressed. Tridimensionality is expressed in terms of range images. The recognition model is based on a vector space representation using an orthonormal image basis. The recognition meth

We present an approach for scale invariant 3D object detection based on phase Fourier transform (PhFT). Three‐dimensionality is expressed in terms of range images. The PhFT of a range image gives information about the orientations of the surfaces i

We present a novel method of three‐dimensional object recognition independent of illumination conditions. The recognition model is based on a vector space representation using an orthonormal basis generated by the Lambertian reflectance functions o

We present a method for coding the information of a 3D object into a representation on a unit sphere. The coding is based on mapping the phase Fourier transform of the range images of the object onto the sphere. This procedure creates a unique object

The problem of three-dimensional (3-D) object recognition is addressed. Range images permit the description of 3-D surfaces with a significant reduction of the complexity of the processing. The encoding of range images as phase gives a simple and str

In color pattern recognition, color channels are normally processed separately and afterward the correlation outputs are combined. This is the definition of multichannel processing. We combine a single-channel method with nonlinear filtering based on
