What is feature level image fusion?

What is feature level image fusion?

3.1 Introduction. Feature-level fusion is an intermediate-level fusion process that uses the feature information extracted from the original information of each source for comprehensive analysis and processing. Feature-level fusion is a fusion of information at the intermediate level.

What is pixel level image fusion?

Pixel-level image fusion is designed to combine multiple input images into a fused image, which is expected to be more informative for human or machine perception as compared to any of the input images.

What is image fusion in image processing?

The image fusion process is defined as gathering all the important information from multiple images, and their inclusion into fewer images, usually a single one. In computer vision, multisensor image fusion is the process of combining relevant information from two or more images into a single image.

What is IHS in remote sensing?

IHS transform is one of the commonly used remote sensing image fusion methods. I, H, S, respectively, reflect the characteristics of three channels: I is the intensity, H is the hue, S is the saturation. I represents the spatial resolution of the image, and H and S represent the spectral resolution of the image.

What is fusion technique?

The multisensor information fusion technique is a major information support tool for system analysis and health management that can cross-link, associate, and combine data from different sensors, reducing target perception uncertainty and improving target system integrated information processing and response …

Is based on pixel level computing?

Pixel-based systems are able to recognize the measurable inconsistencies that are presented at the pixel level. Configuration based strategies are used to influence the measurable relationships given by a particular lossy compression plot.

What is the purpose of image fusion?

The purpose of image fusion is to combine information from multiple images of the same scene into a single image that ideally contains all the important features from each of the original images. The resulting fused image will be thus more suitable for human and machine perception or for further image processing tasks.

What is a fusion method?

Fusion welding is a process that uses heat to join or fuse two or more materials by heating them to melting point. External application of pressure is not required for fusion welding processes, except for resistance welding, where substantial contact pressure is required during welding for sound joining.

What is the role of IHS in image fusion?

I. The IHS technique is one of the most commonly used fusion techniques for sharpening. It has become a standard procedure in image analysis for color enhancement, feature enhancement, improvement of spatial resolution and the fusion of disparate data sets [29].

What is IHS transformation?

Summary. The inverse hyperbolic sine (IHS) transformation is frequently applied in econometric studies to transform right-skewed variables that include zero or negative values. We show that regression results can heavily depend on the units of measurement of IHS-transformed variables.

What is multi scale fusion?

The final image is obtained by fusing the original two input images and the virtual image via a state-of-the-art MEF algorithm. …

How small is a pixel?

Pixels, abbreviated as “px”, are also a unit of measurement commonly used in graphic and web design, equivalent to roughly 1⁄96 inch (0.26 mm).

How is the feature level image fusion achieved?

The feature level image fusion is achieved by region based fusion scheme,,. In region based image fusion, initially an image is partitioned into a set of regions. The different features of these regions are extracted. The appropriate features from all the source images are merged to get the fused image.

Which is a survey on region based image fusion methods?

A first hand survey on region based image fusion is presented in Section 2. Decision level image fusion techniques are based on the outputs of initial object detection and classification task [10], [11], [12]. Usually, a preliminary decision from the feature based image fusion serves as the input to the decision level fusion.

How is image fusion used in surveillance applications?

In surveillance applications, image fusion can fuse the information across the electromagnetic spectrum, (e.g., visible and infrared band) for night vision. In response to the requirements in real applications, the researchers have been very active in proposing more effective image fusion methods.

How is multi-scale transform used in image fusion?

Multi-scale transform is a recognized tool that has been demonstrated to be very useful for image fusion and other image processing applications. Fig. 3 illustrates the schematic diagram of a generic multi-scale decomposition based image fusion scheme.
