In this work we present the design of an automatic infant cry recognition system that classifies three different kinds of cries, which come from normal, deaf and asphyxiating infants, of ages from one day up to nine months old. The classification is done through a pattern classifier, where the crying waves are taken as the input patterns. We have(More)
BACKGROUND Crying is the first neurophysiological demonstration of the newborn. The acoustic analysis of crying episodes can provide useful information in the early diagnosis of several pathologies. METHODS We carried out a spectrographic cry analysis of 40 infants with several diseases such as neonatal asphyxia, breathing disorders, deafness and(More)
Crying is the only communication way recently born babies have to express their needs. Several studies have shown that infant cry can be a valuable tool to determine the different infant’s emotional, and physiological states. With the aim in usefully applying the crying information, in this paper we present the use of Fuzzy Support Vector Machines (FSVM)(More)
BACKGROUND The automatic analysis of facial expressions is an evolving field that finds several clinical applications. One of these applications is the study of facial bradykinesia in Parkinson's disease (PD), which is a major motor sign of this neurodegenerative illness. Facial bradykinesia consists in the reduction/loss of facial movements and emotional(More)
The objective of our work is the development of a natural language dialogue system for information retrieval with multimodal input and multimedia output. Overall, the system consists of three phases: input analysis, information and knowledge management and output generation. The dialogue system is designed for consulting old Mexican historical documents. In(More)
This paper presents the process of design and implementation of a hybrid system which is able to perform the required operations to dynamically determine the maximum production capacity, inside a factory plant, according to the production or sales plans, at any given period. This task is done along with optimizing the assignment of the different products,(More)
This paper describes the design criteria followed for the implementation of an Intelligent Dome System (IDS) for buildings. It was designed as a Client/Server system on a Blackboard Architecture. The IDS is conformed by 9 Specific Control Groups (SCG), and one central control (Dome). Each SCG is designed as a Multi Agent System and the Dome as a Fuzzy(More)
Crying in babies is a primary communication function, governed directly by the brain; any alteration on the normal functioning of the babies’ body is reflected in the cry (Wasz-Höckert, et al, 1968). Based on the information contained in the cry’s wave, the infant’s physical state can be determined; and even pathologies in very early stages of life detected(More)
Automatic Infant Cry Recognition (AICR) process is basically a problem of pattern processing, very similar to the Automatic Speech Recognition (ASR) process (Huang, Acero, Hon, 2001). In AICR first we perform acoustical analysis, where the crying signal is analyzed to extract the more important acoustical features, like; LPC, MFCC, etc. (Cano, Escobedo and(More)
OBJECTIVE We analyzed the spectrograms of the cry of deaf children and compared the results with those of normal children. MATERIAL AND METHODS Twenty deaf children (0-2 years of age, both sexes) and 20 normal hearing children of both sexes within the same age range were studied. The deaf cases were selected from patients with high-risk pregnancies who(More)
