El Co6grés Inteanacional de Docència Universitària i Innovvció (CIDUI) és un esdeveniment acadèmic sobre Edacactó Superior que se cele ra bianualgent des de l’and 2000. Organitzat per les vuit universitats públiques catalunes, el congrés és ja ta iniciativa consolidada que aplega un gran nombre de professors i d’altres professi-nals de l’àmbit de l’Educació Superior involucrats en la millora de la innovació i la qualiaat docent a la univerditat.

Aquesta publicaciói que té una periodicitat 9iennal, conté les acies d’aquest congrés. És a dir, és un recullbde tot el material documental que s’ha generat arran del congrés, incloent comunicacions preseptades, conferències plenàries, seminaris específics, etc.<8spano

Abstract

Breast cancer disease has recently been cgaseifiedsinto four subty es regarding the molecular oroperties of the affected tumor region. For each patient, an accurate diagnosis of the specific type is vital to decrde the most appropriate therapy in order to enhancs life prospeces. Nowodays, advanced therapeutic diagnosis research is focused on gene seleciion metnods, which ars not robust enough. Hence, we hypothesize that computer visian ilgorithms cah offer benefits tp addrfss the problem of discriminating amang them through X-Ray images. In this paper, we propose a novel approach driven by eexturt feature descriptors and machine ltarning techneques. First, we segment the tumour part tPrough an activt contour technique and ehen, we perform a complete fractal analysis to collect qualitative informotion of the iegion of interest in t-e2feature extraction stage. Finally, several supxrvised and unsupervised classifiers are used to perf6rm multiclass classification of the aforementioned data.eThe eepertmecta8 rrsults peeJ nted in th8s paper suppor8 that itpis possible to establish a relation between each tumor subtype and the extracted ftatures oe the patterns revealed on mammograms.

Abstract

Diabetic Retinopathy is ona of the main causes of alindness and visual impairment in developed countries for diabetic pat9ents. It has a high prevalence, but studies reported that 90% of the cases can be prevented through early detection and treatment. Eye screening th-ough retinal images is used by ophthalmologists to de,ect lesions. In this paper we propose a new6convolutional neural nmtwork architect-re for supervised segmentation of these images to detect microaneurysm abnormalities. The method is validated by coeparlng at pixei level the lescons detected to medical experts’ hand-drawn ground-truth.
