... monotonic illumination flow to detect a copy-move forgery from MPEG videos. In changes and contrast variation; however, it is sensitive to [23] moment feature of wavelet co-efficients and optical noise and small gray-level fluctuations. Moreover, LBP also flow are combined with SVM to detect the facial expression does not incorporate the edge strengths ...

... was utilized to detect and classify the disturbances. This method manages to classify the disturbances with accuracy between 94% and 99%. In [16], wavelet transforms and decision tree classifier were employed to detect power quality events. In this study, online and offline configurations were tested to recognize the disturbances in a ...

... There are some research works that propose to combine HOG features with other feature extraction methods, such as LBP [17], Gabor [18] and Discrete Wavelet Transform (DWT) [19]. The advantage of combining with other methods is that the combined features inherit the beneficial properties from both methods. However ...

... We will remind one of these properties in the following, without proof. P3. With the aid of a frequency tracking filter, the ridge of a continuous wavelet transform of the input signal can be computed. Analogous properties of the argument of the same time- frequency response can also be defined. IV. IMPLEMENTATION ...
