Abstract:Voice signals are one of the most popular data types. They are used in various applications like security systems. In the current study a method based on wave equation was proposed, implemented and tested. This method was used for correct feature array generation. The feature array can be used as a key to identify the voice signal without any dependence on the voice signal type or size. Results indicated that the proposed method can produce a unique feature array for each voice signal. They also showed that th… Show more
“…Data histogram [20][21][22][23] is an array of elements, each of which points to the repetition of one value in the data set [24][25][26][27]. Calculating the wave file histogram is an initial task of the proposed later in this paper method of features extraction.…”

“…Here we have to select the data set, number of clusters, and the centroid of each cluster: Data set = 15,15,16,19,19,20,20,21,22,28,35,40,41,42,43,44,60,61,65 Clusters=2; C1=16, C2=22 Perform the following tasks while centroid changing:…”
Digital audio signal is one of the most important data type at present, it is used in various vital applications, such as human knowledge, security and banking applications, most applications require signal identification and recognition, and to increase the efficiency of these applications we must seek a method to represent the audio file by a small set of values called a features vector. In this paper research we will introduce an enhanced method of features extraction based on k-mean clustering. The method will be tested and implemented to show how the proposed method can reduce the efforts of voice identification, and can minimize the recognition time a set of voice extracted features must be used instead of using the voice wave file.

“…Color images have a high resolution, thus they have a huge sizes which make the process of matching color images byte by byte a process that requires great effort and time, which force us to seek a method capable to generate a few unique values to represent any color image. Many texture methods are now used to create color image features [13], [14], many of these methods are based on local binary pattern (LBP) method such as modified LBP method, these methods provide high efficiency by requiring a small extraction time [15], [16], but these methods are sensitive to image rotation, any image rotation will generate new different features, broking the features stability condition [17]. Some of the methods used in extracting the image features depend on statistically treating the image matrix and calculating some statistical parameters such as the arithmetic mean and standard deviation, and using the values of these parameters as the image features.…”
Color digital images are widely circulated in various means of communication, and these images are used in multiple and vital applications, which forces us to search for easy and effective ways to represent the digital image with a set of unique values that facilitate the process of retrieving or recognizing the digital image. A digital image is mostly made up of a group of objects that can be used to generate a features vector for an image that can be used as an image identifier. In this paper, we will present a set of easy procedures through which it is possible to retrieve objects in a digital image and how to use the information of these objects toform the properties of the image. We will also demonstrate the flexibility of the presented procedures in using a wide range of object information to formulate unique image values that can be used as properties for digital image retrieval or recognition.
“…Microphones convert the fluctuating air pressure into electrical signals, voltages or currents, in which form we usually deal with speech signals in speech processing, speech signal is emerges from a speaker's mouth, nose and cheeks, is a one-dimensional function (air pressure) of time [1], [2], [20]. Microphones convert the fluctuating air pressure into electrical signals, voltages or currents, in which form we usually deal with speech signals in speech processing [17], [18], [19]. Human speech is an analogue signal which can be converted to digital signal by applying sampling and quantization as shown in figure 1.…”

“…The speech file histogram can be calculated based on local binary pattern (LBP) operator calculation [24], [25], and here we introduce the following method as shown in table 2 to calculate LBP histogram for each speech file. To reduce the number of values used to represent the speech signal file we have to seek a method to extract a set of features values [17], [18], [19,[20], which must be unique and small and easily used to identify the speech file.…”
Human speech digital signals are famous and important digital types, they are used in many vital applications which require a high speed processing, so creating a speech signal features is a needed issue. In this research paper we will study more widely used methods of features extraction, we will implement them, and the obtained experimental results will be compared, efficiency parameters such as extraction time and throughput will be obtained and a speedup of each method will be calculated. Speech signal histogram will be used to improve some methods efficiency.
