Bilateral filtering is an edge-preserving filtering technique; it employs both geometric closeness and radiometric similarity of neighboring pixels. A 2-dimensional implementation of the bilateral filter and its float closeness

however

are not suitable for hardware implementation and computationally expensive. In this paper

a modified bilateral filtering algorithm is proposed. It improves the bilateral filtering in three aspects: designing integer geometric closeness

restoring image in 1-dimensional and adaptively choosing control parameter of radiometric similarity. Experiments show that the modified bilateral filtering can achieve better performance.
