A single-chip image sensor used in almost all consumer and in some professional-grade digital cameras today is affixed with an alternating pattern of spectrally shifted (in the electromagnetic wavelength sense) color filters to each pixel location. The arrangement of color filters, which are typically the canonical color triples (i.e. red, green, blue), is called color filter array (or CFA) [1,...

We propose a 2D display and camera arrangement for video communication systems that supports both spatial information between distant sites and user mobility. The implementation of this arrangement is called the “surrounding back screen method.” The method enables users to freely come from and go into other users’ spaces and provides every user with the direct pointing capability, since there i...

In this study a recently developed neuroevolution method, HyperNEAT, is applied to new tasks in order to learn more about its characteristics in general and for the tasks specifically. The tasks required directly processing raw image data, including some from a robot-mounted camera, requiring the neural networks to directly process hundreds or thousands of inputs. The tasks included object reco...

AIMS To establish a three dimensional reconstruction of an invasive breast carcinoma using basic laboratory equipment to evaluate and characterise the spatial arrangement of the parenchymal cells of the breast. METHODS One hundred and twenty eight sequential 4 microm sections (20 microm apart) of the tumour were stained immunohistochemically with an epithelial specific marker (AE1/AE3) or tum...

The most realistic information about the transparent sample such as a live cell can be obtained only using bright-field light microscopy. At high-intensity pulsing LED illumination, we captured primary 12-bit-per-channel (bpc) response from an observed microscope equipped with high-resolution (4872x3248) image sensor. In order to suppress data distortions originating interactions elements in op...

Although the video surveillance system plays an important role in intelligent transportation, limited camera views make it difficult to observe many traffic events. In this paper, we collect and combine flow variables from multi-source sensors, propose a PITED method based on Random Forest (RF) Permutation importance (PI) for event detection. This model selects suitable by means of permutation ...

Magma-filled dikes may feed erupting fissures that lead to alignments of craters developing at the surface, yet details activity and migrating eruptions crater row are difficult monitor hardly understood. The 2021 Tajogaite eruption Cumbre Vieja, La Palma (Spain), lasted 85 days developed a pronounced alignment be related changes within volcano edifice. Here, we use COSMO-SkyMed satellite radar...
