Super-Resolution Based Demosaicking For Full Motion Video SWIR Multi-Spectral Sensor

Spectral Tracking Using an Oblique Looking, Video Rate, 9-Band, SWIR Multispectral Camera

“…Bad pixels in the array were then replaced with the average value of the nearest pixels of the same band. The images were then demosaicked using linear interpolation to reduce the amount of spectral anomalies that may result from demosaiking which seeks to improve spatial resolution over the spectral unit-cell size [5]. and 3204 DN for the bright signature (red, B in Fig.…”

Increasing Resolution of Multi-Spectral Mosaic-Array Cameras

“…Then the weight can be reintroduced in a different way to maintain spectral content by defining relationships between pairs of different spectral images n and n', where , ′ is the correlation between bands n and n' and is the band affinity parameter responsible for normalization. To emphasize the local nature of the relationship between the bands, the weights , ′ are defined on spectral clusters [8]. Spectral clustering of data is performed using the k-means technique with the preset number of clusters.…”

“…Indeed, pixels form the same unit color cell observe slightly different points in space producing images shifted from each other by an increment of a FPA pixel pitch. In this case, higher spatial frequency information can be recovered using principles of multi-frame super-resolution (SR) [5][6][7] that are modified to handle images collected at different wavelengths [8]. For clarity this approach will be referred to as multi-band SR.…”
