I completed my PhD in ECE under the dual CMU-Portugal program.
My advisors were professor Manuela Veloso and professor João Paulo Costeira.
am mostly interessed in object recognition from multiple partial views,
collected from a mobile robot equiped with an RGB camera.
represent such partial views, I have introduced a heat diffusion based
descriptor, the Partial View Heat Kernel (PVHK). Such descriptor allows
to represent not only the geometry of an object, but also its color and
To combine the multiple partial views taking into consideration the
robot movement, I use a Particle Filter. Furthermore, to take into
account that I want to estimate the object class, and not the robot
position, I introduced a Similarity Based Resampling, which takes into
account the uncertanty from ambiguous and non-discriminative partial
views. (code will follow soon)
During my PhD I also developed an algorithm for Joint Assignment and
Stitching of Non Overlapping Meshes (JASNOM). JASNOM creates a manifold mesh of the whole object, without requiring previous registration of the two meshes on the same coordinate system. (code will follow
As a Post-Doctoral researcher at Instituto Superior Tecnico, I have been working on automatic tile panel assembly. This problem is similar to jigsaw puzzle assembly, but tiles have little texture that does not always aligns properly accronss abuting sides. Namely, I have adapted the previously heat based descriptor to introduce an afinity measure that is more resilient to this noise than current metrics.
