Isolated digits were extracted from the database to form a separate dataset the CVL Single Digit Dataset.
Individual binary digits may be extracted from individual hexadecimal digits, and octal digits can be extracted from one or two hexadecimal digits.
In brief, total RNA was extracted from forelimb digit I, forelimb digits II-V and all five hindlimb digits using TRIzol® Reagent (Invitrogen, Cat. No. 15596026, US), treated with DNase I (Roche, Cat. No. 04716728001, Germany) and converted to double stranded cDNA using Oligo dT beads.
Total RNA were extracted from forelimb digit I, forelimb digits II-V and all five hindlimb digits of two H. armiger (Bat H1 and H2, Table 1), using TRIzol® Reagent (Invitrogen, Cat. No. 15596026, US) and treated with DNase I (Roche, Cat. No. 04716728001, Germany).
Isolated handwritten digit patterns are then extracted from the localized postal-code region.
To train the AV-HMMs, digit utterances were randomly extracted from the database and then used to generate sequences of different duration, e.g., "7 5 4" and "2 0 3 9".
Figure 4 Plots of smooth spectra corresponding to MFCC feature along with linear (DFT) spectra of a stable voiced frame extracted from the digit "OH" signals having average pitch value of (a) 85 Hz and (b) 310 Hz.
Figure 13 Plots of smooth spectra corresponding to MFCC feature along with linear (DFT) spectra of a stable voiced frame extracted from the digit "OH" signals having average pitch value of (a) 310 Hz (original), and (b) 190 Hz (after transformation of the average pitch of the signal from 310 Hz by factor of 1. 6).
This can be further verified by comparing the smooth spectrum of a stable voiced portion extracted from a digit "OH" signal having original average pitch value of 310 Hz with that obtained after reducing the average pitch of the signal by a factor of 1.6 as shown in Figure 13.
These distortions can be seen in the smooth spectrum of the stable voiced portion extracted from the digit "OH" signal having average pitch value 310 Hz when compared with that of the 85 Hz average pitch signal as shown in Figure 4.
