Thermal infrared is an alternative method in determining the thermal distribution in almost everything. Thermal infrared camera captures the raw thermal images. These raw thermal images most likely to have an unwanted entities. To have an accurate setup especially in hot spot detection system, the raw image must be properly processed. By applying the Discrete Wavelet Transform (DWT) in thermal infrared...
Traditional methods for Natural Image Understanding can both be computationally expensive and lack robustness. A recently proposed technique for Natural Image Understanding, based on sparse coding, is computationally less expensive and has demonstrated the capability to correctly identify objects from particular types of noisy images. In this paper we examine the ability of this sparse coding technique...
We propose a novel method to reduce both blocking and ringing artifacts in compressed images and videos. Based on the directional characteristics of ringing artifacts along edges, we use a directional fuzzy filter which is adaptive to the direction of the ringing artifact. The filter exploits the spatial order, the rank order and the spread information of the signal together with the position of the...
