Dual technique compression
View Patent ↗Systems and methods for ensuring that images are compressed in a format that may be decompressed at a speed that is acceptable to a particular user and/or viewing environment are disclosed herein.
1. A method of preparing images for use by a computing device comprising one or more hardware processors, the method comprising:
receiving, at the computing device, a compressed image comprising data generated by compressing an image file using a first compression technique;
determining whether the first compression technique provides at least a threshold decompression speed;
in response to determining that the first compression technique does not provide at least the threshold decompression speed:
decompressing the compressed image;
recompressing the decompressed image using a second compression technique that does provide at least the threshold decompression speed; and
storing the recompressed image in a memory so that the recompressed image is available for decompression on the computing device or another computing device;
in response to determining that the first compression technique does provide at least the threshold decompression speed, without recompressing the compressed image using the second compression technique, storing the compressed image in the memory so that the compressed image is available for decompression on the computing device or another computing device.
2. The method of claim 1 , wherein the second compression technique is selected based on one or more of a processor speed of the computing device, one or more video capabilities of the computing device, one or more preferences of a user of the computing device, and/or one or more characteristics of the image file including a modality of the image file, a size of the image file, a slice thickness represented in the image file, one or more anatomical structures represented in the image file, a color depth of the image file, and/or a bit depth of the image file.
3. The method of claim 1 , further comprising:
determining, by the computing device, the threshold decompression speed.
4. The method of claim 1 , wherein the threshold decompression speed is provided by a user of the computing device or is based on preferences provided by the user of the computing device.
5. The method of claim 4 , wherein the preferences indicate different threshold decompression speeds for different modalities of medical images.
6. The method of claim 1 , wherein the memory comprises a random access memory or a flash memory.
7. The method of claim 1 , further comprising:
requesting the image file from a server storing the image file or the compressed image.
8. A computing system comprising:
one or more hardware processors;
a tangible computer readable medium storing software modules configured for execution by the one or more hardware processors, the software modules including at least:
a receiving module configured to receive a compressed image comprising data generated by compressing an image file using a first compression technique;
a decision module configured to determine whether the first compression technique provides at least a threshold decompression speed;
an optimization module configured to:
in response to determining that the first compression technique does not provide at least the threshold decompression speed:
decompress the compressed image;
recompress the decompressed image using a second compression technique that provides at least the threshold decompression speed; and
transmit the recompressed image to a memory so that the recompressed image is available for decompression on the computing device or another computing device; and,
in response to determining that the first compression technique does provide at least the threshold decompression speed, without recompressing the compressed image using the second compression technique, transmit the compressed image to the memory so that the compressed image is available for decompression on the computing device or another computing device.
9. The computing system of claim 8 , wherein the second compression technique is selected based on one or more of a processor speed of the computing device, one or more video capabilities of the computing device, one or more preferences of a user of the computing device, and/or one or more characteristics of the image file including a modality of the image file, a size of the image file, a slice thickness represented in the image file, one or more anatomical structures represented in the image file, a color depth of the image file, and/or a bit depth of the image file.
10. The computing system of claim 8 , wherein the decision module is further configured to determine the threshold decompression speed.
11. The computing system of claim 8 , wherein the threshold decompression speed is provided by a user of the computing system or is based on preferences provided by the user of the computing system.
12. The computing system of claim 11 , wherein the preferences indicate different threshold decompression speeds for different modalities of medical images.
13. The computing system of claim 8 , wherein the memory comprises a random access memory or a flash memory.
14. The computing system of claim 8 , further comprising:
requesting the image file from a server storing the image file or the compressed image.
15. A non-transitory tangible computer readable medium having modules including software instructions encoded thereon, the modules configured for execution by a computing system having one or more hardware processors, the modules including:
a receiving module configured to receive a compressed image comprising data generated by compressing an image file using a first compression technique;
a decision module configured to determine whether the first compression technique provides at least a threshold decompression speed;
an optimization module configured to:
in response to determining that the first compression technique does not provide at least the threshold decompression speed:
decompress the compressed image;
recompress the decompressed image using a second compression technique that provides at least the threshold decompression speed; and
transmit the recompressed image to a memory so that the recompressed image is available for decompression on the computing system or another computing device; and,
in response to determining that the first compression technique does provide at least the threshold decompression speed, without recompressing the compressed image using the second compression technique, transmit the compressed image to the memory so that the compressed image is available for decompression on the computing system or another computing device.
16. The non-transitory tangible computer readable medium of claim 15 , wherein the second compression technique is selected based on one or more of a processor speed of the computing system, one or more video capabilities of the computing system, one or more preferences of a user of the computing system, and/or one or more characteristics of the image file including a modality of the image file, a size of the image file, a slice thickness represented in the image file, one or more anatomical structures represented in the image file, a color depth of the image file, and/or a bit depth of the image file.
17. The non-transitory tangible computer readable medium of claim 15 , wherein the decision module is further configured to determine the threshold decompression speed.
18. The non-transitory tangible computer readable medium of claim 15 , wherein the threshold decompression speed is provided by a user of the computing system or is based on preferences provided by the user of the computing system.
19. The non-transitory tangible computer readable medium of claim 18 , wherein the preferences indicate different threshold decompression speeds for different modalities of medical images.
