Digit recognition for license plate recognition is a core process, simplicity on the algorithm to recognize digits on the LPR context is of importance, given that there is an ever increasing vehicle flow and need for recognizing license plates on different environments and applications such as: unattended parking lots, automatic toll collection, traffic supervision, access control of restricted...

The revised Speech Perception in Noise (SPIN) test and the Dichotic Sentence Identification (DSI) test have been used to help evaluate speech-recognition capabilities in elderly people. We evaluated the test-retest reliability of these measures for 17 subjects aged 63-82 years. The DSI and revised SPIN tests were administered at 65, 75, and 85 dB SPL, with a total of three presentations at each...

OBJECTIVES In this study, the authors assessed the potential utility of a recently developed questionnaire (Evaluation of Children's Listening and Processing Skills [ECLiPS]) for supporting the clinical assessment of children referred for auditory processing disorder (APD). DESIGN A total of 49 children (35 referred for APD assessment and 14 from mainstream schools) were assessed for auditory...

Sensorineural hearing loss is commonly accompanied by reduced frequency selectivity, which causes the larger adverse effect of masking. To cope with this issue, some studies have addressed the effects of dichotic listening to reduce the masking between contiguous frequency bands. This paper investigates sound image localization perceived in both dichotic and diotic listening conditions, as well...

Brain event-related potentials (ERPs) to probe tones in a dichotic complex tone test were recorded from right-handed depressed patients (n = 44) and normal subjects (n = 19) at homologous sites over left and right hemispheres (F3, F4; C3, C4; P3, P4; O1, O2). There were no differences between groups N1 or P2 amplitude, but patients had smaller P3 amplitude than did normal subjects. Depressed pa...

INTRODUCTION The obstructive sleep apnea syndrome (OSAS) is a respiratory disorder that occurs during sleep and it is relatively common in children. AIM The goal of this paper is to verify if there is a relationship between the obstructive sleep apnea syndrome (OSAS) and auditory processing. METHODS In order to do that, three groups of children ranging in age from 5 to 11 were studied, incl...

The authors found splenial lesions to be associated with left ear suppression in dichotic listening of consonant-vowel syllables. This was found in both a rapid presentation dichotic monitoring task and a standard dichotic listening task, ruling out attentional limitations in the processing of high stimulus loads as a confounding factor. Moreover, directed attention to the left ear did not impr...

Signed digit (SD) number systems provide the possibility of constant-time addition, where inter-digit carry propagation is eliminated. Such carry-free addition is primarily a three-step process; adding the equally weighted SDs to form the primary sum digits, decomposing the latter to interim sum digits and transfer digits, which commonly belong to {–1, 0, 1}, and finally adding the tra...
