Cable and wire detection system for aircrafts [Hava araçlari için tel ve kablo tespit sistemi]
(2013)
EDlines is a robust and accurate line segment detector that is known to run 11 times faster than the popular (and fastest known) method of LSD, while avoiding necessity of parameter adjustments. In this work, this detector ...
The Mycielski78 compression algorithm
(IEEE, 2006)
The Mycielski predictor is a prediction algorithm that utilizes the infinite past of a data sequence. The algorithm resembles the LZ77 compression method. LZ78, on the other hand, is a dictionary based lossless compression ...
Steepest descent algorithm for block wavelet transform filter coefficients that generate orthogonal transform matrix [Dik Dönüşüm matrisi üreten blok dalgacik süzgeç katsayilarinin en dik i·niş algoritmasi i·le bulunmasi]
(2008)
It's known that the transform matrix generated by Block Wavelet Transform (BWT) is orthogonal. Eigenvector matrix of the autocorrelation matrix obtained in Karhunen-Loeve transform is also orthogonal. This matrix is used ...
On the orthogonality of block wavelet transforms [Blok dalgacik dönüşümlerinin dikligi üzerine]
(2006)
In this paper, orthogonality of Block Wavelet Transforms (BWT) is shown. First the orthogonality of one-stage and two-stage Block Wavelet Transforms is shown, then the result is generalized for multi-stage Block Wavelet Transform
2-D analysis and compression of power-quality event data
(IEEE-Inst Electrical Electronics Engineers Inc, 2004)
This paper introduces a novel two-dimensional (2-D) representation of the power quality event data. 2-D discrete-time wavelet transform is applied to the 2-D representation of real-life event data. The proposed representation ...
A motion adaptive wavelet-denoising for frame-rate up-conversion [ÇerçEve Hizi Artirimi için Hareket Duyarli Dalgacik Düzeltme]
(Institute of Electrical and Electronics Engineers Inc., 2016)
This study introduces a method that employs a wavelet zerotree-based shrinkage algorithm motion-adaptively-combined with optical flow estimation for video frame rate up-conversion. In the method, an optical flow estimation ...
A 3D Lifting Based Method Augmented by Motion Compensation for Video Coding
(IEEE, 2009)
This study introduces a spatio-temporal lifting based algorithm to be used in compression of video signals. The temporal correlation of consecutive frames causes temporal redundancies, which are subject to lifting-like ...
Classifier-based offline feature selection and evaluation for visual tracking of sea-surface and aerial targets
(Spie-Soc Photo-Optical Instrumentation Engineers, 2011)
An offline feature selection and evaluation mechanism is used in order to develop a robust visual tracking scheme for sea-surface and aerial targets. The covariance descriptors, known to constitute an efficient signature ...
Prediction error PDF improvement in multichannel predictive coders [Çok kanalli öngörüye dayali kodlayicilarda öngörü hata dagiliminin i·yileştirilmesi]
(2006)
In this paper, multichannel predictive image coder outputs are investigated within each channel. By obtaining prediction error biases and compensating them in each channel, the total error histogram is sharpened
Segmentation based coding of human face images for retrieval
(Elsevier Science BV, 2004)
A coding method for face images by segmenting face regions Such as eyes, mouth, etc. is introduced. Each region is removed from the face image, leaving a smoothly interpolated background which is suitable for efficient ...
