Pdf Scale Invariant Feature Transform The scale invariant feature transform (sift) with its related image descriptors in terms of histograms of receptive field like image operations have opened up an area of research on image based matching and recognition with numerous application areas. For better image matching, lowe’s goal was to develop an interest operator that is invariant to scale and rotation. also, lowe aimed to create a descriptor that was robust to the variations corresponding to typical viewing conditions. the descriptor is the most used part of sift.

Sift scale invariant feature transform introduction sift: scale invariant feature transform. sift method was developed in the early 2000s. its accuracy and robustness were significantly higher than previous template matching methods. Take dog features from differences of these images‐producing the gradient image at different scales. if the feature is repeatedly present in between difference of gaussians, it is scale invariant and should be kept. compute histogram of gradient directions to identify the most dominant direction. This article proposes modifications to the scale invariant feature transform (sift), that improve the repeatability of detection and effectiveness of matching in the presence of distortion, while preserving the characteristics of invariance to scale and rotation.
