due to substantial effect of classification of resource models on future mine planning, one should come with an accurate method of estimation to guarantee that the minimum error is acquired in the estimation process. the known world class cu-mo deposit, sarcheshmeh porphyry deposit (central iran) selected as the study area. the hypogene zone of the deposit was chosen as the space in which estim...

The interpolation techniques for the time-of-flight estimation have been under study. The ToF estimation was done using the direct correlation technique of the sampled signal. More accurate estimation was done using interpolation between the samples. Three interpolation techniques for discrete direct correlation are discussed: linear interpolation of zero crossing, imaginary part of direct corr...

Time interleaved sigma-delta converter is a potential candidate for multi-mode wideband analog to digital (A/D) converters dedicated for multistandard receivers. However, the interpolation by zeros recquired to compress the useful signal bandwidth at the input of the sigma-delta modulator imposes constraints on the implementation of the analog part leading to a very large die area due to the hi...

watermarking implant information into a digital signal like audio, Picture, or video. Reversible Picture watermarking can bring back the original picture without any distortion after the hidden data is extracted. In this paper, we present a novel reversible watermarking scheme using an interpolation procedure, which can embed a large amount of covert data into Pictures with imperceptible modifi...

Spatial interpolation is an important feature of a Geographic Information System, which is the procedure used to estimate values at unknown locations within the area covered by existing observations. This paper constructs fuzzy rule bases with the aid of a Selforganising Map (SOM) and Backpropagation Neural Networks (BPNNs). These fuzzy rule bases are then used to perform spatial interpolation....

Absfrucf-Cubic convolution interpolation is a new technique for resampling discrete data. It has a number of desirable features which make it useful for image processing. The technique can be performed efficiently on a digital computer. The cubic convolution interpolation function converges uniformly to the function being interpolated as the sampling increment approaches zero, With the appropri...

Soon after Lee and O’Sullivan proposed a new interpolation algorithm for algebraic soft-decision decoding of Reed-Solomon codes, there have been some attempts to apply a coordinate transformation technique to the new algorithm, with a remarkable complexity reducing effect. In this paper, a conceptually simple way of applying the transformation technique to the interpolation algorithm is propose...

Preserving edge structures is a challenge to the image interpolation algorithms to reconstruct a high resolution image from a low resolution counterpart. We propose a new guide edge linear interpolation technique via address filter and data fusion. For a pixel to be interpolated, two sets of observation are defined in two orthogonal directions, and each set produces an estimated value of the pi...

Reversible Data hiding is a process of hiding information into a cover image. There are various techniques used for hiding secret data. Audio, video, image, text, and picture can be used as a cover medium in data hiding. In images, Reversible Data Hiding (RDH) is a method which is very helpful in the recovery of original cover after the inserted message is extracted. This vital method is broadl...
