2. OBJECTIVE
To develop a system for automatic translation
of static gestures used by dumb and deaf persons
into audible speech understandable by a common
person.
3. INTRODUCTION
• Sign recognition system act as a interpreter
between common people and socially aided
people.
• It captures the gesture shown by the deaf and
dumb people and convert immediately into
known language.

Technology
Explanation
Skin segmentation and region growth approach is used
for image recognition
9. Harris Corner Detection
• In the harries corner detection we
calculate the cim , r, c.
• Cim - binary image marking corners.
• r - Row coordinates of corner points.
• c - Column coordinates of corner points
10. Histogram
• Histograms can be used to provide
useful image statistics Information
• It plots the number of pixels for each
value
• Histogram we are using the num-bins
function
12. K-NN Algorithm
• This approach is used to match the key points
calculated from the capture image using the
harries and sift.
• Now the key points matched with the database
image.
• IDX = knn search searches the reference data
set to find the k-nearest neighbours of each
query point represented by each row.
13. Text to Speech
• Serial board communication kit is used to
convert Text to Speech.
• This Kit contains PIC Microcontroller,
Selector, Voice recorder, Amplifier, Speaker,
Step down transformer.
