SUM-MODIFIED-LAPLACIAN FUSION METHODS EXPERIMENTED ON IMAGE STACKS OF PHOTONIC QUANTUM RING LASER DEVICES COLLECTED BY CONFOCAL SCANNING LASER MICROSCOPY

In cazul anumitor tipuri de investigatii prin microscopie pot fi obtinute rezultate doar daca operatiile aferente sunt executate avand ca suport imgini cu o focalizare uniforma. Una dintre tehnicile prin care se pot obtine astfel de reprezentari este fuziunea imaginilor. In acest articol prezentam doua metode de fuziune a imaginilor bazate pe operatorul Sum-modified Laplacian (SML) care realizeaza o imagine fuzionata, compusa din mai multe imagini corespunzand sectiunilor optice achizitionate prin microscopie confocala cu baleiaj laser (CSLM). In prima metoda imaginea fuzionata este alcatuita din blocuri al caror raspuns fata de operatorul SML este maxim, iar in a doua metoda aceasta este alcatuita prin medierea ponderata a blocurilor, ponderea fiind reprezentata de raspunsul la acelasi operator. For certain types of microscopy investigations results can be achieved only if the connected operations are performed on images of uniform focus. One of the techniques for obtaining this kind of representation is image fusion. We present two Sum-modified Laplacian (SML) image fusion methods which output a fused image built based on a stack of images collected by Confocal Scanning Laser Microscopy (CSLM). In the first method the fused image consists of blocks of highest response to SML, while in the second method it consists of mean weighted blocks, where the weight is the response to the same operator, SML.
