Efficient image categorization
View Patent ↗A method for efficiently categorizing images on a computer system is disclosed. A series of related images that are to be categorized are ordered by time of capture, and category levels for input of category information by a user are displayed. The category levels include a highest-category level and a lowest-category level, where the highest-category level has a low frequency of data change between the series of related images, and the lowest-category level has a high frequency of data change between the series of images. A first image is then categorized by allowing the user to enter highest-category level data and lowest-category level data. A next image in the series is then categorized by leaving the highest-category level data unchanged, and automatically selecting the lowest-category level data for reentry by the user, thereby eliminating the need for the user to reenter the highest-category level data.
1. A method for efficiently categorizing images on a computer system, comprising the steps of:
(a) ordering a series of related images that are to be categorized by time of capture;
(b) displaying category levels for input of category information by a user, wherein the category levels include a highest-category level and a lowest-category level, the highest-category level having a low frequency of data change between the series of related images, and the lowest-category level having a high frequency of data change between the series of related images, wherein any intermediate category levels have medium frequency of data change between the series of related image;
(c) categorizing a first image by allowing the user to enter highest-category level data and lowest-category level data, and as the user enters data, comparing the data with previous entries, and when a match is found, automatically entering the previous entry to thereby reduce inconsistent terminology;
(d) categorizing a next image in the series by leaving the highest-category level data unchanged, and automatically selecting the lowest-category level data for reentry by the user, thereby eliminating the need for the user to reenter the highest-category level data.
2. The method of claim 1 wherein step (d) further includes the step of:
(i) comparing date and time differences between the first image and the next image to automatically detect a category change from the first image to the next image; and
(ii) if a category change is detected, automatically selecting an appropriate category level for reentry by the user.
3. The method of claim 2 wherein step (b) further includes the step of:
(ii) displaying a thumbnail of the current image being categorized.
4. A computer readable medium containing program instructions for efficiently categorizing images on a computer system, the instructions for:
(a) ordering a series of related images that are to be categorized by time of capture;
(b) displaying category levels for input of category information by a user, wherein the category levels include a highest-category level and a lowest-category level, the highest-category level having a low frequency of data change between the series of related images, and the lowest-category level having a high frequency of data change between the series of related images, wherein any intermediate category levels have medium frequency of data change between the series of related images;
(c) categorizing a first image by allowing the user to enter highest-category level data and lowest-category level data, and as the user enters data, comparing the data with previous entries, and when a match is found, automatically entering the previous entry to thereby reduce inconsistent terminology;
(d) categorizing a next image in the series by leaving the highest-category level data unchanged, and automatically selecting the lowest-category level data for reentry by the user, thereby eliminating the need for the user to reenter the highest-category level data.
5. The method of claim 4 wherein step (d) further includes the step of:
(i) comparing date and time differences between the first image and the next image to automatically detect a category change from the first image to the next image; and
(ii) if a category change is detected, automatically selecting an appropriate category level for reentry by the user.
6. The computer readable medium of claim 5 wherein instruction (b) further includes the instruction of:
(ii) displaying a thumbnail of the current image being categorized.
