An study on ear detection and its applications to face detection

[EN]OpenCV includes di erent object detectors based on the Viola-Jones framework. Most of them are specialized to deal with the frontal face pattern and its inner elements: eyes, nose, and mouth. In this paper, we focus on the ear pattern detection, particularly when a head pro le or almost pro le view is present in the image. We aim at creating real-time ear detectors based on the general object detection framework provided with OpenCV. After training classi ers to detect left ears, right ears, and ears in general, the performance achieved is valid to be used to feed not only a head pose estimation system but also other applications such as those based on ear biometrics.

Climate change and the evolution of loggerhead sex-ratio in Cabo Verde

[EN] Global warming can affect nesting success of sea turtles due to the rise of the sea level and the subsequent increased inundation or erosion of nesting beaches. Moreover, it can reduce male production to levels that can alter reproduction due to their temperature dependant sex determination (TSD). Now, mean nest temperatures all around the world predict a predominance of female hatchlings, and this trend may increase with global warming in the next decades.

The eastern Atlantic juveniles of loggerhead sea turtles: Where do they come from and how do they distribute?

[EN] After hatching, loggerhead sea turtles (Caretta caretta) enter in the sea and start the ocean phase of their lives, where juveniles inhabit pelagic feeding areas during 6-12 years. In the Atlantic Ocean, the central and the eastern feeding grounds harbor loggerhead juveniles from different nesting populations, constituting the designated mixed stocks. We studied the distribution of juveniles in the Eastern Atlantic comparing mtDNA sequences from canarian individuals with samples from Azores, Madeira and the Atlantic coast of Andalusia.
