A Wavelet-Based Template Locating Criterion for Electronic Digital Image Stabilizer Application

چکیده
Template selection is an important step in a feature based electronic digital image stabilizer (EDIS). In this paper, we present a wavelet-based criterion for template locating that can be used in block-based electronic digital image stabilizers. Tlus criterion computes the vertical and horizontal details of an image and employs them for template selection. The performance of this criterion is compared with an information-based algorithm in two ways. First it is used to evaluate registration of real and noisy images. For second evaluation. an electronic digital image stabilizer is designed and the stabilized sequences generated by using information-based algorithm and our algorithm have been compared. The evaluations show that our criterion has better performance than entropy based criterion.

Weighted Multiple Bit-Plane Matching, a Simple and Efficient Matching Criterion for Electronic Digital Image Stabilizer Application
ABSTARCT In this paper we propose two new matching criteria for template matching. The performance evaluation of these two criteria is applied to electronic digital image stabilizer (EDIS) application. These two criteria are based on bit-plane matching (BPM) criterion, where four decimated bit-planes are used in our criteria. These criteria can be realized using only Boolean functions; hence th...
متن کاملAn electronic digital image stabilizer based on stationary wavelet transform (SWT)
In this paper we present a new SWT based algorithm for electronic digital image stabilization application. In our proposed algorithm, we first estimate the translational motion by projecting the vertical and horizontal details of stationary wavelet decomposition in level 2. These parameters are used as initial estimation of motion's parameters. Then, we use several feature points and a gradient...

Removing noise from images is a challenging problem in digital image processing. This paper presents an image denoising method based on a maximum a posteriori (MAP) density function estimator, which is implemented in the wavelet domain because of its energy compaction property. The performance of the MAP estimator depends on the proposed model for noise-free wavelet coefficients. Thus in the wa...

Image data require huge amounts of disk space and large bandwidths for transmission. Hence, imagecompression is necessary to reduce the amount of data required to represent a digital image. Thereforean efficient technique for image compression is highly pushed to demand. Although, lots of compressiontechniques are available, but the technique which is faster, memory efficient and simple, surely...
متن کاملA Robust Digital Image Watermarking Scheme Based on DWT
In this paper a wavelet-based logo watermarking scheme is presented. The logo watermark is embedded into all sub-blocks of the LLn sub-band of the transformed host image, using quantization technique. Extracted logos from all sub-blocks are merged to make the extracted watermark from distorted watermarked image. Knowing the quantization step-size, dimensions of logo and the level of wavelet tra...
