The present invention relates to a method for the simultaneous identification of one or more chemical compounds contained in a sample, from an analytical measurement of a pool of two or more of the said samples, wherein a measured intensity of a first and second signal is representative for an abundance of respectively the first and second chemical compound in the first sample, and a measured intensity of a third and fourth second signal is representative for an abundance of respectively a third and fourth chemical compound in the second sample, wherein respectively the first and third, and the second and fourth compound may be the same or different, wherein the signal intensities are organized in a matrix aij of m columns and n rows, wherein n is 2 and corresponds to the number of chemical compounds in the pool, wherein m 2 and corresponds to the number of samples in the pool, wherein aij corresponds to a signal intensity measured for compound i present in sample j, (1) wherein: (2) and : (3).


The invention provides a sensing device for obtaining geometric referenced multi-spectral image data of a RoI in relative movement with respect to the device, the sensing device comprising: a first and second 2D sensor element, the device obtaining subsequent multi-spectral images during said relative motion of the Rol with respect to the device thus providing distinct spectral information for parts of a Rol using the first element; and providing, using the second element, an image of the Rol for generating geometric referencing information to be coupled to the distinct spectral information; each element capturing a sequence of frames at a respective frame rate. The first frame rate is higher than the second frame rate. The device generates intermediate geometric referencing information to be coupled to frames of said first sequence of frames for which no synchronous frame from said second sequence of frames is available, derived from temporally similar frames from the second sequence of frames.


The invention pertains to a method for geometric referencing of multi-spectral data in a sequence of images, the images containing distinct regions representing imaged radiation in respective distinct wavelengths, the method comprising: selecting a subset from the sequence of images, said subset containing a plurality of images, each image of which represents a field of view that overlaps with a field of view of at least one other image in the same subset; generating a 3D model by performing photogrammetric 3D reconstruction on the images in the subset; estimating a displacement and a yaw between pairs of successive images of said sequence of images; and using said 3D model and said estimated displacement and yaw to calculate photogrammetric parameters for images of said sequence of images that are not in said selected subset. The invention also pertains to a corresponding system and a corresponding computer program product.

The invention pertains to a method for transforming a set of spectral images, the method comprising: dividing the images in said set in identically arranged areas; for each of said areas, calculating a predetermined characteristic across said set of images; and, for each of said images, renormalizing intensity values in each of said areas in function of said predetermined characteristic of said area. The invention also pertains to a corresponding computer program product and a corresponding image processing system.


According to an aspect of the present invention, there is provided a method for performing photogrammetric 3D reconstruction of objects imaged in a sequence of images, the images containing distinct regions representing imaged radiation in respective distinct wavelengths, the method comprising: selecting a plurality of subsets from the sequence of images, each one of the plurality of subset containing a plurality of images, each image of which represents a field of view that overlaps with a field of view of at least one other image in the same subset; generating a set of intermediate 3D models by performing photogrammetric 3D reconstruction on the images in respective ones of the subsets; and recombining the intermediate 3D models from the set of 3D models into a combined 3D model.


Apparatus (30) for plasma processing of a continuous substrate (16), comprising a first plasma torch. The first plasma torch comprises a first electrode (11), a second electrode (12) arranged opposite the first electrode to define a first plasma discharge chamber (13) between the first and second electrodes. The first plasma discharge chamber (13) comprises an inlet (131) and an outlet (132) for passing a plasma forming gas (133) between the first and second electrodes. The apparatus further comprises an afterglow chamber (17) in fluid communication with the outlet (132) of the first plasma discharge chamber and a transport means for continuous transporting the substrate (16). The afterglow chamber (17) comprises a substrate inlet (172) and a substrate outlet (173) arranged at opposite sides of the outlet (132) of the first plasma discharge chamber (13). The transport means is configured to transport the substrate from the substrate inlet (172) to the substrate outlet (173) through the afterglow chamber (17) and such that the substrate is kept remote from the first plasma discharge chamber (13) while being processed by plasma activated species flowing from the outlet (132) of the first plasma discharge chamber into the afterglow chamber (17). The substrate inlet (172) comprises an aperture having a cross-sectional size (G1) substantially smaller than a cross-sectional size (G2) of the afterglow chamber (17) at the outlet (132) of the first plasma discharge chamber (13). The apparatus can further comprise a second plasma torch (32) aligned with and arranged opposite the first plasma torch (31), with the afterglow chamber (17) interposed between. The outlets (132, 232) of the first and second plasma torches face each other and exhaust plasma activated species into the afterglow chamber (17).

the present invention provides a method for the selective recovery of a metal of interest, such as Cr, from metal-containing slag material via a one-step oxidative alkaline leaching process wherein the waste material is contacted with an alkaline leaching solution comprising an alkali metal hydroxide and an alkali metal or alkaline earth metal hypochlorite whereby simultaneously (i) the metal (Cr) is leached from the metal-containing slag and (ii) an aqueous alkaline leach liquor comprising the metal(s) of interest (Cr) is obtained. This way, the valuable metals can be recovered from this waste material and, at the same time, the environmental impact of these waste materials is reduced and their recyclability is improved by removal of the detrimental metal(s).
