This paper assesses the implementation of scale-and rotation-invariant feature detectors on Cellular Processor Arrays (CPA). Scale- and rotation-invariant feature detectors are complex image processing algorithms with a high computational burden in the low-level image processing stage due to large-neighborhood convolution-type operations. Such operations are used to generate the so-called scale-space...
The residue from the extraction of agar-agar from Gracilaria debilis was evaluated as a biosorbent for the removal of linear alkyl benzene sulphonate from aqueous solution. The adsorption was studied in batch systems at 25°C and at different pH values. A preliminary screening showed that the average size of the sorbent did not affect the adsorption characteristics. The isotherm equilibrium data...
