Object Identification and Colour Recognition for Human Blind

چکیده
Navigation Assistance for Visually Impaired (NAVI) is a vision substitute system designed to assist blind people for autonomous navigation. NAVI working concept is based on ‘image to sound’ conversion. The vision sensor, which is mounted on a sunglass, captures the image infront of blind user. NAVI processing unit processes the captured image and enhances the significant vision data by employing a set of image processing procedures. The processed information is then presented as a structured form of acoustic signal and it is conveyed to the blind user using a set of earphones. This paper proposes a new object identification and colour recognition module for NAVI system. Image processing techniques are proposed to identify objects in the captured image and then the processed image is transformed into stereo sound patterns. Colour information from the interested object is evaluated to determine the colour of the object. The colour output is informed to the blind user through ‘verbal voice’.

The Selective Attention for Identification Model (SAIM): Simulating Visual Search in Natural Colour Images
We recently presented a computational model of object recognition and attention: the Selective Attention for Identification model (SAIM) [1–7]. SAIM was developed to model normal attention and attentional disorders by implementing translation-invariant object recognition in multiple object scenes. SAIM can simulate a wide range of experimental evidence on normal and disordered attention. In its...
متن کاملAn efficient parameters selection for object recognition based colour features in traffic image retrieval
This paper proposes a novel technique for object identification and representation in complex traffic scene based on the colour features integrated with line detection techniques. Objects of interest (vehicles) are represented by using a Minimum Bound Region (MBR) with a reference coordinate. Object appearance is represented by colour-based features computed from the proposed technique. The per...
متن کاملHuman Object Recognition Using Colour and Depth Information from an RGB-D Kinect Sensor
Human object recognition and tracking is important in robotics and automation. The Kinect sensor and its SDK have provided a reliable human tracking solution where a constant line of sight is maintained. However, if the human object is lost from sight during the tracking, the existing method cannot recover and resume tracking the previous object correct...
متن کاملCoding of Visual Object Features and Feature Conjunctions in the Human Brain
Object recognition is achieved through neural mechanisms reliant on the activity of distributed coordinated neural assemblies. In the initial steps of this process, an object's features are thought to be coded very rapidly in distinct neural assemblies. These features play different functional roles in the recognition process--while colour facilitates recognition, additional contours and edges ...
متن کاملThe effect of colour congruency on shape discriminations of novel objects.
Although visual object recognition is primarily shape driven, colour assists the recognition of some objects. It is unclear, however, just how colour information is coded with respect to shape in long-term memory and how the availability of colour in the visual image facilitates object recognition. We examined the role of colour in the recognition of novel, 3-D objects by manipulating the congr...
