Portable and fast text detection
In this paper, we describe an efficient pipeline for real-time text detection to be implemented on different architectures, with particular reference to smart phones. The text detection pipeline is based on a rather standard segmentation followed by a classification of each segmented connected component. Segmentation is performed by a linear implementation of MSER, state-of-the-art for text detection, where we control the overall computational cost of the method by computing a set of descriptive features as segmentation goes on. Classification is carried out by a cascade of SVM classifiers, where each layer captures different levels of complexity by means of an appropriate choice of descriptive features and kernel functions. Each detected text element, or character, is finally merged into lines of text and words. Further on, each element can be fed to a multi-class classifier that performs character recognition—this functionality is currently under development. We report experiments aiming at assessing the appropriateness of the text detection procedure, in terms of both performance and speed, when running on both x86 and ARM processors
Le acque del Carso Classico
Classical Karst is approximately 900 km2 and extends from SE of the Isonzo River to Postumia town and it
is characterized by the large variety of karst features. For this reason, this area is the best example of karst worldwide.
Classical Karst hydrogeological model has been subdivided in three different sectors: one in which the surface waters
become underground and therefore feed the deeper karst aquifer, one in which these waters moves in the deeper part
of the aquifer and are nourished by local precipitation and one in which these waters finished in the Adriatic Sea or in
local springs that feed several small lakes and the large spring of Timavo River.
Classical Karst is marked by deep and well developed karstic features. In fact, in the Italian part of the Classical Karst
more then 3000 caves have been found. Of these, 150 are more then 100 m developed and ten of them are extended
more then 1000 m. In addition, in this area of the Karst, 80 dolines with a diameter of more then 100 m are present and
limestone karren pavements extend for several km2. Six kilometers after the Skocjan sinkhole, the Timavo underground
waters run into the deeper galleries of the Abisso dei Serpenti (Kačna Jama) located at 140 m a.s.l. Approximately 15
km southward, the Timavo waters runs at 10-20 m a.m.s.l. in the deepest part of four vertical cavities that are 300 to
370 deep and are located approximately 20 km northward of the resurgence area. One of these, the abyss of Trebiciano,
has been known for long time, whereas the others named Grotta of Kanjeduce, the abyss of the Strsinkna doline
and the Grotta Meravigliosa di Lazzaro Jerko have been discovered recently. The spring system is formed by the Timavo
Spring located in San Giovanni of Duino, the Doberdò and Pietrarossa Lakes and by small springs that feed the
Lisert and Moschenizze channels (for a total area of 30 km2) and by the coastal-marine springs along the Trieste’s Gulf
and Duino Aurisina villages (approximately 8 km). The waters in these spring system are from different aquifers that are
interconnected between them and have an average discharge capacity of 40 m3s-1 and a maximum of 175 m3s-1.
Hydrochemically these waters have similar ion concentrations. However, changes have been found in the water hardness
and in chlorine quantities. This data together with the oxygen stable isotope results allow to dive them into:
- Timavo Spring, with Alto Timavo waters (Reka River);
- Sardos e Moschenizze Sud Springs, feed by the Isonzo River waters and with waters from the Alto Timavo only during
floods;
- Sablici, Moschenizze Nord, Lisert Springs and Doberdò Lake, characterized by a dual water source: from the Timavo
River and from Isonzo River with a marked increment of these waters towards Moschenizza Nord and Doberdò Lake;
- Aurisina Spring, nourished by karstic waters and with a small contribution from the Alto Timavo
