In this paper, we describe several techniques for detecting tonic pitch value in Indian classical music. In Indian music, the rāga is the basic melodic framework and it is built on the tonic. Tonic detection is therefore fundamental for any melodic analysis in Indian classical music. This work explores detection of tonic by processing the pitch histograms of Indian classic music. Processing of ...

This paper presents a novel method for 2D and 3D shape matching that is insensitive to articulation. It uses the eccentricity transform, which is based on the computation of geodesic distances. Geodesic distances computed over a 2D or 3D shape are articulation insensitive. The eccentricity transform considers the length of the longest geodesics. Histograms of the eccentricity transform characte...

Forest attributes such as tree heights, diameter distribution, volumes, and biomass can be modeled utilizing the relationship between remotely sensed metrics as predictor variables, and measurements of forest attributes on the ground. The quality of the models relies on the actual relationship between the forest attributes and the remotely sensed metrics. The processing of airborne laser scanni...

This paper presents an enhancement to the recent framework of histogram aggregation [1], that enables to improve the matching accuracy while preserving a low computational complexity. The original algorithm uses a fronto-parallel support window for cost aggregation, which leads to inaccurate results in the presence of significant surface slant. We address the problem by considering a pre-define...

We present a new metric between histograms such as SIFT descriptors and a linear time algorithm for its computation. It is common practice to use the L2 metric for comparing SIFT descriptors. This practice assumes that SIFT bins are aligned, an assumption which is often not correct due to quantization, distortion, occlusion etc. In this paper we present a new Earth Mover’s Distance (EMD) varian...

The MODerate resolution Imaging Spectrometer (MODIS) is consisted of cross-track scan mirror and linear arrays of ten detectors. Because 1) the abnormal behavior of the response of each detector, 2) optical cross–talk and shortwave infrared thermal leak, and 3) reflectance, emissivity, or polarization of each scan mirror side are the cause of artificial strips appearing in the images. The histo...

Face identification and verification are parts of a face recognition process. The verification of faces involves the comparison of an input face to a known face to verify the claim of identity of an individual. Hence, the verification process must determine the similarity between two face images, a face object image and a target face image. In order to determine the similarity of faces, differe...

PURPOSE To improve the imaging efficiency of multi-slab three-dimensional acquisitions by decreasing slab overlap and the number of blanked slices. MATERIALS AND METHODS Application of the histogram matching technique for correction of the slab boundary artifact (SBA) due to non-ideal radiofrequency pulse profiles has been proposed. The technique was validated by studying its effectiveness in...

Enhancement of images is applied over all the mammographic images before their diagnosis. The contrast of mammograms is always required to be good so that further investigation of breast cancer images is accurate. Here HE (histogram equalization), HS (histogram specification) and LE (local enhancement) methods are discussed for enhancing and improving the quality of mammographic images and thei...
