A second image processing stage, based on the heat diffusion equation, enables us to obtain the fields of heat sources produced and absorbed by the material during the test.
Moreover, several open beam and dark images have been acquired for later use in the image processing stage.
Our measurement is sent as feedback value to an image processing stage where the correction takes place, building up a "digital image and audio signal" closed loop processing.
At this point, the rest of the processing is carried out only on the data structures that describe these bounding boxes, so that no other image processing stage is required.
The previous system in [7] implements the use of fuzzy techniques for the image processing stage, including the fuzzy histogram equalisation, fuzzy median filter and fuzzy edge detection, for the purpose of one of the important lesion detection in diabetic retinopathy screening microaneurysms.
The selected algorithm, as well as other operations present in the low- and mid-level image-processing stages, matches well with this kind of architectures.
Moreover, several open beam and dark projections have been acquired for later use in the image-processing stage.
The Hue-Saturation-Value (HSV) color space was found useful in obtaining visual features during Image Processing (IP) stage.
Figure11 and Table2 show the segregation results when morphological image processing smoothing stage is applied.
Presented solution integrates 3 classical stages of image processing: pre-processing, medium level analysis (Le. segmentation, labeling), pattern recognition and classification performed by an artificial neural network.
This is especially true for image processing pipelines, where individual stages do much too little work to amortize the cost of loading and storing results to and from off-chip memory.
