Uniform Band Interval Divided Band Selection

IGARSS 2019 - 2019 IEEE International Geoscience and Remote Sensing Symposium, 2019
This paper presents a new band selection approach, called uniform band interval divided band selection (UBIDBS) which uniformly divides a band range into a finite number of band intervals from which a band can be selected from each band interval according to a custom designed band prioritization (BP) criterion. Two BP criteria are introduced.

Band Selection Using Dilation Distances

IEEE Geoscience and Remote Sensing Letters, 2022
In this letter, we adapt the dilation operator from mathematical morphology to propose dilation distances. These dilation distances are then used for band selection in hyperspectral images. It is shown that dilation distances between bands can capture the spatial distance between the objects.

Adaptive hyperspectral band selection

SPIE Proceedings, 2005
We present a new technique for adaptive band selection from hyperspectral image cubes for detecting small targets using an anomaly detector. The proposed technique ensures the selection of lowest number of spectral bands using Mahalanobis distance, maximum affordable extra noise variance, and Constant False Alarm Rate (CFAR) anomaly detector threshold.

Band-selective radiofrequency pulses

Journal of Magnetic Resonance (1969), 1991
A theoretical treatment is given of the general problem of designing amplitude-modulated radiofrequency pulses that will excite a specified band of frequencies within a high-resolution NMR spectrum with uniform intensity and phase but with negligible excitation elsewhere.

Band select ultra wide band unequal power splitter

Microwave and Optical Technology Letters, 2016
In this letter, a new design of a band select ultra wide band (UWB) unequal power splitter suitable for broadband communication systems was presented. To obtain band select characteristics, the proposed structure used broadside coupled lines. The quarter wave transformer in the conventional Wilkinson power splitter was replaced by offset broadside ...

Band Selection: Revisited

2013
We have discussed a method of band selection in Chap. 4 where a specific subset of hyperspectral bands was selected from the input images based on the conditional entropy measure. We have also observed that one can achieve almost similar fusion output by using a small fraction of hyperspectral data.
