MIHS is a feedback system and all the functions are controlled by the microcontroller. Noise being captured as input signal and processed to determine if certain action is required. The MIHS can be modeled at a high-level as shown in the figure below: [pic] From the block diagram‚ ambient sounds are being captured by the microphone of the voice recognition module‚ the EasyVr. The EasyVr will perform noise filtering and convert the signal to digital signal and sends it to the microcontroller

smoothing methods like anisotropic filtering as a lengthy computation time and the fact that diffusion constants must be manually tuned‚ wavelet filtering is faster and automatic. An adaptive smoothing method helps to address the remaining sources of noise and can significantly improve edge detection. In the proposed approach‚ wavelet filtering method is used in which the diffusion constant is tuned automatically.

Mammographic Image quality challenges from Radiography Image clarity‚ or the ability of the mammogram to portray diagnostic information clearly‚ depends on a number of factors‚ which include exposure‚ sharpness‚ contrast‚ and noise . In the image quality category of exposure‚ generalized underexposure was a far more frequent deficiency than overexposure. This is of concern because lesions can be obscured in dense underexposed breast tissue‚ which leads to false-negative mammograms

One of the main application areas in Digital Image Processing methods is to improve the pictorial information for human interpretation. Most of the digital images contain noise. This can be removed by many enhancement techniques. Filtering is one of the enhancement techniques which is used to remove unwanted information (noise) from the image. It is also used for image sharpening and smoothening. Some neighborhood operations work with the values of the image pixels in the neighborhood and the

PAPERS‚ VOL. 52‚ NO. 8‚ AUGUST 2005 Design Procedure for Two-Stage CMOS Opamp With Flexible Noise-Power Balancing Scheme Jirayuth Mahattanakul‚ Member‚ IEEE‚ and Jamorn Chutichatuporn Abstract—This paper presents a basic two-stage CMOS opamp design procedure that provides the circuit designer with a means to strike a balance between two important characteristics in electronic circuit design‚ namely noise performance and power consumption. It is shown in this paper that‚ unlike the previously reported

They are protection to your eyes‚ head and ears (noise). Loud‚ extreme noise can damage an employee’s hearing ability if he or she is not using the right type of protection to prevent the noise. It is extremely important to have the right kind of personal protective equipment for your ears to protect them from the loud noises. There are three main types of ear protection used in a workplace. Earplugs are the most frequently used to help keep the noise level down. Some of which are disposable that are

1 Sound in a Night Club 1.1 Overview Noise in the workplace is a very important aspect to evaluate and make provision for. The consequences of working in an unsuitable environment with regards to noise can be severe and includes the possible risk of permanent hearing damage. In an environment such as a night club‚ the continuous exposure to noise due to the loud music can prove to be dangerous. 1.2 Scope The scope of this project includes measuring and analyzing the sound in Catwalk in order

Types And Causes Of Pollution The term pollution refers to the act of contaminating ones environment by introducing certain hazardous contaminants that disturb the ecosystem and directly or indirectly affect the living organisms of that ecosystem. Pollution in general is the activity of disturbing the natural system and balance of an environment. The increase in the pollution over the years by man has caused severe damage to the earth’s ecosystem. It is responsible for global warming which is leading
