We propose applying of the ridgelet transform to semantic objects segmented using watershed segmentation. The ridgelet transform effectively represents objects with singularities along lines; therefore, it is a powerful tool for coding. Moreover, it can easily rotate blocks in the ridgelet domain. Nevertheless, the targets to be roteted are not rectangular blocks but real objects. For that reason, we divide pictures into semantic objects using watershed segmentation, then convert each object into the ridgelet domain so they can be rotated easily. We experimented in coding and rotating objects.
