–QUANTUM SEGMENTATION TOOL. This is a homemade computer tool to perform enhanced image segmentation. The procedural approach may be parameterised with optimised values for a specific type of data. It uses an algorithm which is inspired by the superposition principle of Quantum Mechanics, in the sense that each particular pixel has a certain probability of being of a certain type (boundary, interior, exterior or noise) and only when an observation is made, by means of choosing a designated threshold value, it gets a concrete state. The procedure is helpful to compute accurate several regions in the same image/layer. –

–QUATERNION 3DP. A homemade computer tool developed based on the basic properties of the quaternion algebra and use the fact that quaternion multiplication can be used as an efficient tool to work with rotations on the 3D-space. This computer tool has several applications on 3D printing, for example it can be used to generate a surface by placing successive planar curves (interpreted as crossed sections) along a structural curve on the 3D-space.

–PRIME RECTANGLE. This is a homemade computer tool to compute optimal rectangular geometry (RoI- region of interest) in arbitrary images with an associated saliency map. Although saliency maps provide an individual relevance measure for each pixel, to find the sub-image (i.e., rectangular region) that contains the set of the most relevant pixels requires an optimisation procedure to define the boundaries of the best RoI. This is achieved by the method devised in the published paper by following an approach based on balancing the amount of relevant information that is included and excluded from the RoI. The results show that such method is capable of finding the most relevant rectangular RoI and thus to extract the optimum sub-images according to the relevance measure given by a generic saliency map. Since the method is not tied to any particular type of images, it finds application in quite different fields, such as salient object extraction and processing in industry and surveillance, image compression using attention modelling, biomedical imaging, etc. –

–MOBI Toolbox. A Matlab procedure for finding finite algebraic structures of a given type, Finite Mobi Algebras in Matlab. –

–BUILD-IT-OPTIMAL. A global optimization computer framework was developed for solar building design applications. Besides the overall framework design, the BUILD-IT-OPTIMAL consists on the identification of different building shapes and their main parameters, the creation of an algorithmic description for these main shapes and the formulation of the objective function, respecting a building’s energy consumption (solar energy, heating and insulation). Additionally, the conception of an optimization pipeline, combining an energy calculation tool with a geometric scripting engine was established. The methods developed leads to an automated and optimized 3D shape generation for the projected building (based on the desired conditions and according to specific constrains). The computer tool can help in the construction of real buildings that account for less energy consumption and for a more sustainable world.
